CHANGELOG:

-MAJORLY improved the level editor. Changes include improved UI, more keybinds to make level building easier, a spawn position marker when in edit mode,  and a background grid while in edit mode, as well as many other smaller changes.

-Fixed numerous bugs relating to the level editor. I don't remember them all
