Corrected issues with textures loading

Corrected shader version depending on OGL version
Corrected bug in gestures module

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

Removed useless tabs and spaces around code

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

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

Also, added support for normals on models

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!

View CHANGELOG for description on small fixes and add-ons

This is a huge update. Check CHANGELOG for details

No-parameters functions use the prototype style FunctionName(void);

We have three vertex buffers: lines, triangles and quads for textures.
Drawing in a desired order could become a nighmare... noww it seems it
works prety well...
