Replace the data/Airports/basic.dat.gz and data/Airports/runways.dat.gz with a single apt.dat.gz file which is in the native X-Plane format. To do this I wrote a front end loader than builds the airport and runway list. Some of the changes I needed to make had a cascading effect, so there are minor naming changes scattered throughout the code.

APTLoader: add missing includes; proper interface for the APTLoader class remove unused members 'last_apt_info' and 'token' The APTLoader methods defined in src/Airports/apt_loader.cxx are now at top level instead of being inside a 'class' definition block, therefore they don't have to be indented anymore.

// Forward declarations
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).

Some additional changes to ensure that FlightGear at least compiles after configuring with --disable-atcdcl. Some substitution code is added in ATC/atcutils.cxx and ATC/atcutils.hxx. Note that the new code doesn't run properly yet. Instead, it is just meant to identify which parts need replacement. Getting that to work will be the next step.
