Bugfix texture export: where textures regarding of their settings would be exported as sprites.
Update texture export: original textures will now be copied to get the pixel values with the correct import settings applied to prevent strange-looking normal maps and color changes.
Folder creation: the required folders will now be created by the tool, no need anymore to save empty folders.
Minor changes: Renamed some variables, testing a new layout error fix, started working on material export.
