Overhual

Functionally, relatively little has changed with this update, compared to the lines of code that have been altered.

• Edddy no longer uses a Qt form for its basic UI layout
• Instead of setting folders for models, materials, maps and blocksets, folders in the resource browser can be set to hidden
• With it, subfolders are now properly supported
• Models are scaled and centered for block preview rendering, to ensure they are visible in their entirety
• A horizontal mode has been added to the map and blocks panels
