- Renamed Begin3dMode() --> BeginMode3D()
- Renamed Begin2dMode() --> BeginMode2D()
- Renamed End3dMode() --> EndMode3D()
- Renamed End2dMode() --> EndMode2D()

Depth test disabled for 2D and only used on 3D; consequently LINES vs
TRIANGLES vs QUADS buffers drawing order maters... but blending also
works ok.

- Added CheckCollisionRayBox() function.
- Updated and improved core 3d picking example (currently working as
expected).

Examples have been renamed for coherence with raylib modules and test
examples have been merged into examples folder.
