35abe6d0ab A number of cosmetic and/or infrastructural changes.
Traffic Manager:
	* Just continue routing until we run out of flights. This change removes one of the major requirements for setting the "Home port" field.
	* Add a time restriction requirement for the aircraft scheduler; this became necessary after removing the limited-to-home-port routing restriction.
	* Added a new field to the heuristics calculation: take into account whether an aircraft has already been used in a previous session. Rotate aircraft assignments for greater variability across sessions.
	* Added a revision number to the cache files, so that old cache results, which are no longer compatible with the new file format, are discarded.

Groundnetwork and traffic control:
	* Added a revision number to the cache files, so that old and incompatible results are discarded.
	* The caching algorithm probably didn't store the correct data for airports that were processed while the user was quite far away. This is now corrected by checking whether the cached elevation data are equal to the generic airport elevation.
AIAircraft:
	* I've been searching for the infamous aircraft bend-over-backward bug, that can occur during initialization, but to no avail yet. The only variable potentially responsible (tgt_vs) wich can explain the irregular jumping behavior, as well as the weird pitch results is initialized in AIAircraft's only constructor (through AIBase), and I can't find any situation in the ground handling code where this variable could get bizarre values. But,
	* a couple of tgt_vs. calculations appear to be completely redundant. This value was calculated twice inside the ProcessFlightplan function, and subsequently again in the updateSecondaryTargetValues function. I have removed the calculations in the process flightplan function, without any apparent side effect.

e65f53b571 Read groundnet node information from the scenery, and (optionally) write it to a cache file. Note that this mechanism should be extended, so that the cache files will be updated whenever the terrain files are changing. The current patch also uncovers a bug, in the sense that the groundnetwork destructor is never called. Presumably this is due to the way airports are allocated in flightgear. Because the ground networks are never saved, I am periodically saving the cache files; but this behavior should probably be changed later on.
The current patch incorporates work contributed by Adrian Musceac.

a7ccae9fca More work on AI/ATC integration:
- Fixed a bug in AI aircraft ground steering code: When aircraft were not moving, the value of headingchangeRate kept increasing to insane levels. Although this was clamped to a maximum of 30 degrees per second, the initial rate could still push the aircraft in the wrong direction. In practice, this bug would be visible when an AI aicraft would be pushed back, when it tended to veer to the right.
 - Make sure that the aircraft slows down well ahead of the pushback point. This change ensures that the AC will actually reach the pushback point. It also ensures a slightly tighter steering range.
 - AI ground steering rate is tuned to 30 degrees per second at a nominal taxispeed of 15. I now modulate the heading adjustment rate by manipulating the adjustment using a non-linear function (the sqrt). This allows for a slightly tighter turn radius at speeds < 15 and slightly looser turns at speeds > 15.
 - The AI Flightplan generation code can return false. This can be used to determine whether any additional AI aircraft may be created. Currently, the function returns false when no more parkings are available. This should limit the build-up of huge AIAircraft tower stacks.
 - The ground network can now graphically display all aircraft actitivy on the ground network by using a virtual marker system.

e54798a8e2 A couple of last-minute patched / bugfixes to mitigate the probability of collisions between user controlled aircraft and AI traffic.
* AI aircraft distance to user proximity detection works again (lat/lon were inverted).
  * The parking uses by the user aircraft is marked as such to prevent it being reused by an AI aicraft
  * AI aircraft won't receive permission for pushback until the user aircraft is at a fair distance.

c478cdd35f Allow the AI Traffic controller to set a transponder code. This code is
used in ATC chatter, and writted to the property, so it can -in principle-
be picked up by the radar.

9cc92035b1 A set of additions related to allow the use of SID and STAR procedures.
The current code still has some rough edges, in particular memory still
needs to be deallocated where possible, and the actual use of the code
needs more testing. This code has been running without noticable problems,
so I think it's ready for some wider exposure. Detailed changes include:
- Finetuning of the SID/STAR data concept.
- Preloading of all SIDs, from one xml file.
- ATC determines which SID should be used and echoes this over the com1 or
  com2 radio.

d24fe19914 One step further toward better integration of AI and ATC systems.
* Changed the runway XX. ATC message to actually report the real
   designated departure runway
 * In case of multiple active runways, select the one with a heading that is
   closest to the direction of the ultimate departure destination / lines up
   with the arrival path.

916240693f Some further work toward adding more AI/ATC messages. This patch provides
some prepratory work for assigning different operations to different
frequencies. It also returns a stub for returning an ATIS message ID.
Currently, the ATIC information ID is hardcoded to "Sierra", which needs
to be replaced by a dynamic ID once ATIS services are fully integrated
with the new trafficcontrol code. At least, it's marginally more realistic
then the previous information XX. :-).

301054204e James Turner: Improved runway management code:
- Runways are now part of an airport, instead of a separate list
 - Runways are no longer represented as a boring struct, but as a class
   of their own.
 -Improved runway access to unify various runway access methods.

17c42deae1 Initial attempt to establish a better integration between AI and ATC code.
Various other patches that have been lingering around for a while:
 * Moved trafficcontrol.[ch]xx from the Airports directory to ATC, where
   it really belongs.
 * AI aircraft will request startup clearance, and ground control will
   approve.
 * Starting AI Aircraft will be pushed back to a predefined holding point
   on the ground network, and wait a while before taxiing out to the runway
