EditFile opens a drawing file (Level or Doodad) in the EditorScene.
The filename can be one of the following:
- A simple filename with no path separators in it and/or no file extension.
- An absolute path beginning with "/"
- A relative path beginning with "./"
If the filename has an extension (`.level` or `.doodad`), that will disambiguate
how to find the file and which mode to start the EditorMode in. Otherwise, the
"levels" folder is checked first and the "doodads" folder second.
