12b6e8952a Avoid crash in ATIS/ATC modules.

ec16f43f86 Use deferred models for scenery tile models.
Instead of PagedLOD nodes use ProxyNodes for models in
scenery tiles. This should lower the amount of PagedLOD nodes
in the active scene. Since the models are part of the to level
tiles they are then paged out once the tile is paged out.

538e632f45 * Updated routing algorithm. Just sorting the schedules by usage heuristics doesn't work well for major multihub airlines.
* Improved groundnetwork routing algorithm. Don't uncesscarily block taxiways. Instead, use a "just-in-time" blocking system. The unblocking algorithm still needs some work, but the current version is already a major improvement over the previous version.
* Some tweaks to the handover from ground to tower controller. Aircraft could refuse to take-off of even refuse to taxi onto the runway. This now seems to be solved.

Log class filters work better when different modules
use different classes :).

9022c6a58d Reintroduce an old bugture: use localizer as dme
Our nav.dat.gz seem to have many bugs regarding paired LOC/DME where
the DME is missing.

A feature has recently been introduced to always use a LOC frequency
as a DME to avoid these issues. However many LOC station do not have
a DME paired at their frequency and this behaviour might be as confusing
as having no DME where one should be.
Before we get new/bugfree navdata, a property can be set to select
the desired behaviour:

if /sim/realism/dme-fallback-to-loc is true or absent, LOC will be
treated as DME (realism is off)
if /sim/realism/dme-fallback-to-loc is false, LOC will be NOT be
treated as DME (realism is on)

30e2db94b1 Add generic "open-browser" command to show URLs or local HTML/text pages.
Replace deprecated "old-help-dialog" command with generic "open-browser".
Can also be used to add links to aircraft manuals in the menubar (local
file or http) , i.e.
<binding>
    <command>open-browser</command>
    <path>Aircraft/ogeL/FlightManual.html</path>
</binding>

02712dc1ad Several Bugfixes:
* Landing AIAircraft now land properly!!!
 * Fixed problems with takeoff scheduling.
 * Untangled several vertical speed calculation algorithms.
 * No more bent-over-backwards and jump-in-the-air AI aircraft initializations.
 * Fixed intermixed target speed and target altitude during climb phase.
 * Implemented beginnings of a "line up and wait" procedure.
 * Tried to use actual runway elevation for calculating the decent profile.

e9d24b05ca Introducing: The new navradio code (WIP)
Here comes the work-in-progres code for a new navradio
implementation. Once completed, it will replace the
old/current navradio implementation.
The new code can be activated by setting
/instrumentation/use-new-navradio=true
at startup. This disables the old navradio implementation.

Current state:
- VOR works pretty good including the new
functionality 'code of confusion'.
- LOC and GS basically work
- backward compatibility (many properties) is to be implemented
