Replaced by fabs() that seem to work ok

Still some work left on camera...

Working in modules configuration flags...

Sincerely, don't like it... it should be ported to quaternions... the
way it manages cameraTargetDistange and cameraAngle is confusing...

Removed internal Camera, not required any more
Removed useless functions

Splitted into:
UpdateCamera()             // Update only camera
UpdateCameraPlayer()   // Update camera and player position

Camera system can be used as standalone module

Some basic to advance templates are provided to be use as base code for
new games

This is a huge update. Check CHANGELOG for details
