Fixed loading files from clicked on when a single instance of the tool is used.
Fixed the UV editor, which loads materails and texture maps properly.
Adjusted loading archives which produced some duplicate file issues when the archive loads the file, and a tree node is clicked on. Ie bntx clearing, but another one would stay in memory.
Fixed bntx replacing.
Basic NCCH support, only romfs previewing for easy ripping and testing for file formats. Writing back and more improvements planned soon.
Save BTI files back.
Add structure based parsing from Kuriimu's IO extension. This will be expanded upon later to parse offsets and other things easier.
