Rework & cleanup CMake project files

- Building with CMake for development is now actually sane
- Split deps into projects and extra files
- Building against external deps should still work but needs testing
- Can now build out of the box without further adjustments as long as SDL(2) is found properly
- Build Lua in C++ mode (so it can use exceptions instead of setjmp/longjmp)
  - Unfortunately we need to enable exceptions for this :(

- Remove these defines:
  * AQUARIA_BUILD_SCENEEDITOR (now always on)
  * AQUARIA_BUILD_CONSOLE (now always on)
  * BBGE_BUILD_ACHIEVEMENTS_INTERNAL (now always on unless BBGE_BUILD_STEAMWORKS is defined)
  * BBGE_BUILD_OPENGL_DYNAMIC (now always on, define BBGE_BUILD_OPENGL_STATIC if needed)
  * BBGE_BUILD_FMOD_OPENAL_BRIDGE (now always on)
- BBGE_BUILD_STEAMWORKS is not actually implemented (any volunteers?)
- Prepare later removal of SDL & the old vc90 project from the repo. See #74 for extra notes.
