- Added Sublime Text project file.
- Added Sublime Text build system.

So user code can use add_subdirectory to build it (similar to what we do
with GLFW or what the projects/CMake/CMakeLists.txt can do).

The CMakeLists.txt checks for an installed raylib and downloads and
installs one if none is found. Afterwards, it builds core_basic_window.c

Update Builder example for raylib 2.0.0.
External OpenAL and GLFW are not required anymore.

Not properly configured, use VS2015.UWP as reference

- Removed unnecesary files
 - Renamed project
 - Reviewed paths
