Got maps *properly* loading in the Godot version of the CUDCrawler editor. I also ended up getting this load map file dialog working on my lunch break. Took me all of ten minutes. I spent *hours* rolling my own file browser in Unity. Ugh. I s'pose it's experience gained... but still!

Up next is getting drawing/erasing walls plugged in. Then saving a map. Once that's done, it's on to re-implementing everything else.

So many things to do, but progress has been good, so I'm satisfied for today!
