It seems Sleep() behaves weird on my computer, disabled by default
returning to the busy wait loop... also re-implemented DrawFPS() to
avoid frame blitting...

- SetWindowPosition(int x, int y);
- SetWindowMonitor(int monitor);

Working in modules configuration flags...

Every part is a resource itself, they are loaded in an array

Also reviewed issue with stdbool when compiling with clang

Useful to set number of repeats for a music, needs to be tested...

Moved to own repo at https://github.com/raysan5/raylib-lua

Only DESKTOP platforms (Windows, Linus, OSX)

Now it uses CharInfo data, this way, it's better aligned with the future
RRES file format data layout for sprite font characters.

Preparing for next version... still some work left... :P

Now program is halted (OS signal call) for required amount of time every
frame, so CPU usage drops to zero, instead of using a busy wait loop.

Lighting is implemented as a raylib example now

...instead of keep polling

Actually, renamed ReadTextFile() from rlgl and make it public

Function names, code formatting...
