Corona must check that gamma Lut are properly set to 2.2

[borisquezadaa]

As Corona need Gamma/LUT=2.2 and taking in to account that from 3DS MAX 2014 and above the output file gamma is not accesible easily, i propose that changing renderer to Corona must set automatically Gamma/LUT to 2.2 (or 2,2 depending on system settings)
AND check for "FileOutGamma=2.2" if changed.

Or at least in the VFB a warning or a way to set that accordingly to avoid issues.

good idea, I will probably add it as soon as some better system for reporting warnings is done.
