#include <simgear/compiler.h>
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.)

James Turner: Convert FGRunway to be heap-based, and inherit FGPositioned. This is a large, ugly change, since FGRunway was essentially a plain struct, with no accessors or abstraction. This change adds various helpers and accessors to FGRunway, but doesn't change many places to use them - that will be a follow up series of patches. It's still a large patch, but outside of FGAirport and FGRunway, mostly mechanical search-and-replace. An interesting part of this change is that reciprocal runways now exist as independent objects, rather than being created on the fly by the search methods. This simplifies some pieces of code that search for and iterate runways. For users who only want one 'end' of a runway, the new 'isReciprocal' predicate allows them to ignore the 'other' end. Current the only user of this is the 'ground-radar' ATC feature. If we had data on which runways are truly 'single-ended', it would now be trivial to use this in the airport loader to *not* create the reciprocal.

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.

FGPositioned clean-ups - apply some desirable changes (such as making members const) which were previously tricky but now easy. Make it possible not to index certain types (used for taxiways) and exclude anonymous items from the name index. Related to this, clean up FGRunway further - remove some public members, and fix a dumb bug of mine, where we create reciprocal entries for taxiways. This should make startup (slightly) quicker, and shrinks FGRunway somewhat.
