Users will have to specify their personal installation of raylib.

This was causing linker errors on OSX

This requires the user to explicitly specify the path to their raylib folder. We need a better way around this (something like what we do for windows would help).

- 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
