2017-10-05	Make GIF decoder more standards complaint	Ryan Harrison
	Fixed issue with unit tests that was causing raw data to be backwards and reverted related LSB -> MSB change that was introduced due to this. If global palette not set then the background colour index should be 0. Check that background colour index is valid when global palette exists. Check if transparency index is valid for the palette of the frame it is being applied to.

2017-10-03	Rewrite how GIF headers are read	Ryan Harrison
	Break up reading the signature and local screen descriptors into seperate functions. Fix a bug in how matching in the signature validation works. Move LSD value assignment to after sufficient data has been confirmed. Convert LSB to MSB methods where they were just wrong. Add unit tests for ReadData, SetInputBuffer, ReadSignature, ReadLocalScreenDescriptor, and ReadHeader.
