Added all public headers to CMake projects, also moved some files around in the public directory. Translation units have been moved to the libraries that were responsible for implementing them, as this game is monolithic.
* All libraries have been isolated from each other, and build into separate artifacts.
* Project has been restructured to support isolating libraries.
* CCrashHandler now calls a callback on crash (setup from core/dllmain.cpp, this can be setup in any way for any project. This callback is getting called when the apllication crashes. Useful for flushing buffers before closing handles to logging files for example).
* Tier0 'CoreMsgV' function now calls a callback sink, which could be set by the user (currently setup to the SDK's internal logger in core/dllmain.cpp).
TODO:
* Add a batch file to autogenerate all projects.
* Add support for dedicated server.
* Add support for client dll.
Bugs:
* Game crashes on the title screen after the UI script compiler has finished (root cause unknown).
* Curl error messages are getting logged twice for the dedicated server due to the removal of all "DEDICATED" preprocessor directives to support isolating projects. This has to be fixed properly!
* Moved 'm_pFileSystem' to 'CSourceAppSystemGroup' (actually belongs there, CAppSystemGroup has to be 0xA8 in size in order for 'm_bDedicated' to line up in 'CModAppSystemGroup').
* Prefixed all static functions with 'Static' to avoid name collisions.
Destruvtor is prepended on every class in-engine. Reflected in SDK. Also removed extraneous method from ICvar causing other methods below it to misalign after the IAppSystem change.
