Samples count was not properly calculated on WAV loading

Start removing old rRES functions.

Added SetupViewport so high-DPI fix applies to EndTextureMode

log2() is not available in some standard C library implementations

Replaced LUA by Lua

Added some missing contributors...

Develop branch integration

[games] Fix building the games on Linux by adding missing libs

texture.mipmaps value needs to be updated, so, texture must be passed by
reference instead of by value

Updated Physac to new version (library and examples)

BMFont loading has been improved to support unordered chars and extended
characters (up to 255)

Mask was wrongly applied to 8-bit font image, it generated dark borders
on the font. Grayscale image has to be considered as the alpha mask for
a completely white image to use it correctly.

Functions that need to manage big data arrays don't work properly, that
functionality should be reviewed...
