Camera Fixes

Browse source 
-=-=-=-=-=-=

-Object Picking and orthogonal camera related functions fixed (i hope)
-Going to preview mode in the camera shows a frame with the correct game aspect ratio
-Changed Camera API and properties a little t make it more straightforward
-Fixed bug in shader compiler.

-Fixed bug in ShaderGL
