Complete review of matrix rotation math
Check compressed textures support
WIP: LoadImageFromData()

- Camera system moved to a separate module [camera.c]
- WIP: Added customization functions for camera controls
- Added custom shaders support on batch drawing
- Complete redesign of textures module to support multiple texture
formats (compressed and uncompressed)

Moved functions: LoadShader(), UnloadShader()
Add support for PVR textures compressed/uncompressed
WIP: Detect available extensions for compressed textures

Support multiple texture formats (uncompressed and compressed)
Postprocessing shaders support
Model struct redefined and improved
Extended loading functions for Textures and Models
Simplified functions: DrawPlane(), DrawQuad()
Deleted functions: DrawPlaneEx(), DrawGizmoEx()
Now Text module only depends on Textures module
Shapes: Reviewed functions to low lines/triangles usage
Removed useless tabs and spaces around code

Extended default raylib font system to support Latin-1 Supplement
characters

Corrected GetMouseWheelMove()
Corrected camera system
Reviewed cubicmap resolution (collision detection)
Added QuaternionTransform()
WIP: Raycast system (not working)
WIP: Reviewing axis-angle rotations...

Shader system has been completely redesigned
Added support for multiple texture color modes

LoadCubicmap() supports custom texture rectangle (from texture atlas)
for every cubic-face.
CheckCollision*() for spheres and bounding-boxes.

Custom shaders for models
Postprocessig on FBO (in progress)
Some useless spaces removed

Improved makefiles!

Also, added support for normals on models

Edited to better accomodate to multiple platforms

Corrected some bugs on the way...
Automatically convert textures to POT on RPI and WEB

[models] Added DrawQuad()

Added PLATFORM_WEB support (emscripten-webgl)
[audio] Added LoadSoundFromWave()
[textures] Added LoadTextureFromImage() to replace CreateTexture()
Some TraceLogs edited...

[core] Added SetMousePosition()
[models] LoadHeightmap() - Corrected textures bug
[raymath] Functions renaming
[WEB] Prepare environment for emscripten!
