Subject: General: * Fixed a variety of server browser issues with mods based
 on this SDK * Fixed many warnings on various platforms * Added source code
 for fgdlib and raytrace * Updated many source files with the latest shared
 source from TF2.

OSX:
* Added support for Xcode 4.6
* Switched OSX builds to use Xcode instead of makefiles
* Moved libs from src/lib/osx32 to src/lib/public/osx32 or src/lib/common/osx32 to match windows better.

Linux:
* Moved libs from src/lib/linux32 to src/lib/public/linux32 or src/lib/common/linux32 to match windows better.
