It seems there are some platform-dependant issues

- Removed useless templates
- Reviewed all Makefiles
- Rework some code for Android support
- Added resources to advance template

Notice that requries libraries are directly taken from
raylib/release/libs/android folder and nativeLoader.java is generated by
Makefile on the go

Using shared libraries just don't work...

OpenAL Soft and raylib compiled for release and stripped

...almost there! raylib already works, issues with OpenAL Soft
linkage...

- Renamed some folders
- Added some files for testing
- Removed useless files

For some reason it's not working properly... :(

Updated to latest version, not tested

..to avoid blending issues with white background

Removed glew from basic_game makefile as glew is not part of the raylib package (no glew in mingw).

... and switch from debug build to release

I've added .PHONY targets and fixed "clean" recipe.
