Sprint #16 - 11/23 to 12/7

Got started on the editor, although I didn't really make much progress. That said, I can at least tick off the following.

•  Add a new room for the editor.
•  Add a button to the menus to access the editor.
•  Add a play-from-code room.
•  Add a button to the menus to play shared levels.

I also spent a bit of time thinking about how to implement the serializer. I need to get some of the basics of the editor in place to be able to make something workable for that though.

Also, I predict that the UI and UX for the editor is going to turn out to be the hardest part. I can't really imagine a good way to handle the various palettes a user will need easy access to.

For this sprint, I'll continue working through the list I posted last time.
