Minor update

Features

• The Gui keybinding will now be able to close the Main Gui screen for quicker toggling
• The dirt background is gone

Fixes

• When saving an edit to an existing block, you will go back to the Block list instead of closing the entire gui.

Dev notes

I have refactored the entire codebase to fall inline with my other mods. This means anyone doing an active check for a mod using com.xray.xray will now need to update their check to pro.mikey.xray
