Split runway and taxiway into separate classes, with a (new) common base. This makes taxiways smaller (important since at present there are so many). Restructure the apt.dat parsing code to use a helper class instead of one long function, and to do less work when parsing the file. Some of these ideas come from Yon Uriarte's patches - thanks Yon.

turn a few #include paths from the "foo" form to <foo> The quotes form is normally only used for headers with path relative to the including file's path, though the standard doesn't strictly mandate this. This is consistent with the rest of sg/fg, it makes the code's intent clearer and helps to find headers. (And it's a few milliseconds faster, too.)

Implement a persistent cache for navigation data. Cache the parsed navigation and airport data in a binary file to reduce startup times and memory consumption (since only referenced FGPositioned elements are held in memory). Data will be reimported when the mod-time of any input file is changed. If a global file is changed (nav.dat, awy.dat, apt.dat, etc), the cache will be completely rebuilt, which takes approximately 30 seconds on moderate hardware. (Future work may reduce this).

Major update to the AI code: * New features - More realistic descent paths - Separation during descent and approach - ATC approach controller (still silent) - inbound traffic flow will start immediately * Bug fixes - Properly handle vertical speed when on ground - Departing aircraft now wait for taxiclerance before moving - Traffic manager waits for proper weather initialization - Fixed instabilities in the preferential runway usage code - Fine tuning of waypoint following code.
