Refactor marker-beacons to be distinct from FGNavRecord. This is a big space saving for beacons, but since they're surprisingly few (in nav.dat), not a an enormous saving in real terms. The major motivation is that marker beacons don't behave like other NavRecords for radio interaction - they have no ident, frequency or range (in the sense that NavRecord means them).

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.)

#include <Navaids/markerbeacon.hxx>
Fix warnings identified by updated XCode. Mostly unused private vars, for various reasons.

using std::string;
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).
