v0326

Changes:

• Added support for UE4 ORM textures (Red = AO, Green = Roughness, Blue = Metalness)
• Some parameters can be left empty and FVM will automatically use a completely blank texture instead
• Added some clarification to the comments and config file
• Changed VMT generation to get more accurate results
• The VMT will now be located in the same folder as the VTFs
• The VMT will now show which values were used to generate it
• Fixed a bug where materials would turn out very dark and shiny if the color map had an alpha channel
• FVM will now replace the generated VTFs and VMTs regardless of whether they already existed and/or changed at all
• Normal map generation is more optimized now
• Did some code clean-up (still not very polished)
