Level Editor

I've been working on the Level Editor for The Render Engine for some time now.  It's really starting to come together.  It has core functionality in it which allows you to draw actors (sprites) and levels (tile maps) in the interface.  Right now it's still in its infancy, but it's starting to feel like an editor.  Eventually it will be how you set up a level for a 2d tile mapped game.  You can try it out by grabbing v2.0.0 from GitHub and firing up the Tile Mapping Demo.  When the "game" loads, press the F4 key and you should get the editor.  It isn't very intuitive right now, but it at least shows progress.
