GBitmap Changes:
Added all other formats to gbitmap that we support
gbitmap now supports cubemaps
added converters for all these other formats
added stb_image_resize for extrudemips so we can extrude mipmaps for all other formats
GFXTextureManager
Can now directly make cubemaps and texture arrays based on the GFXTextureProfile
API implementations for all functions that cubemaps and arrays needed
Processed core, tools and default modules to utilize assets
Converted all console types that were string based, such as TypeImageFilename to utilize const char*/the string table, which avoids a lot of type swapping shenanigans and avoids string corruption
Removed unneeded MainEditor mockup module
Removed some unused/duplicate image assets from the tools
