...moved to internal AudioBuffer structure as totalFramesProcessed, now time measure works again... but there is some problem with looping...
Also note some inconsistencies between frames and samples, it seems those concepts are not considered correctly in the code.

I'm not sure why the clean command is so complex (especially given that find -type f -executable | xargs rm -fv works!)
but I fixed the version as is, to support x-pie-executable which was preventing it deleting anything on my system...

All data should be properly initialized by now

They are not automatically unloaded when unloading the model!

Reduced bunnymark limits

Renamed for consistency with similar functions

- Mesh, Shader, Material structs have been reviewed to minimize size when passed by value, all required code has been reviewed.
 - GetCollisionRayModel() reviewed to avoid pointer, not required because model is not modified inside the function
 - UnloadMesh() reviewed, pointer not required
 - CheckCollisionRay*() parameters name reviewed

- Updated Makefile with new examples

Changes:

 - Font structure has been redesigned, CharInfo structure contained character rectangle within font texture, it has not much sense, considering that it was an information relative to the font atlas generated and not the character itself, so character rectangles have been moved out from CharInfo to Font.
 - CharInfo included a data parameters to contain character pixel data (usually grayscale), generated on TTF font generation. It was inconsistent with other fonts types, so, now CharInfo includes directly an Image of the glyph.
 - REDESIGNED: GenImageFontAtlas(), additional recs parameter added, loaded and filled inside the function to export atlas characters rectangles, instead of silently modify the input CharInfo data.
 - REVIEWED: ImageTextEx(), funtion retrieved the font atlas image from the GPU, that was slow and problematic in several platforms. Now it uses directly the CharInfo image. Support for unicode codepoints has also been added.
 - REDESIGNED: ImageDraw(), now it includes an additional parameter, the color tint, not only it could be useful for several situations but also function signature is more consistent with similar functions.
 - ADDED: ImageFromImage() to generate a new image from a piece of another image.
 - REVIEWED: GetNextCodepoint(), renamed parameters to be more clear.

Also all examples and games that were affected by those changes have been reviewed.

- Capital letters at beginning
- for loop spacing and brackets
- Functions naming for consistency
- Example following examples template
- Other tweaks

* added multi channel sound replay to raudio
added -fPIC to Makefile for Linux
added simple lighting and audio multi channel to examples Makefile

* not properly reporting audio buffer pool size...

a minor issue: where the location of the file "raylib.rc.data" is wrong, and this will cause an error in compilation.
