- don't read the channel always from tacan[0] (even if the existence of a second tacan may not be likely) - remove some dead code - simplify <name>/<number> handling - let a listener watch over input props and search for new channel/frequency - allow to set channel number as one number (rather than as single digits), as some aircraft may prefer this (the ch53 does so); this is to be set in /instrumentation/tacan[n]/frequencies/selected-channel[0]

TACAN: fix distance calculations and some other problems. - Calculate line of sight distance instead of distance over ground - Do a nav cache update if carrier_nav.dat.gz timestamp has changed - Allow comments in carrier_nav.dat.gz - "Fix" range calculations (still does not take terrain/weather and other influences into account)

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).
