Display MainGame.mnu and map in ordoor simultaneously

It's a complete mess for now - many things are out of place or shown
when they shouldn't be - and we can't move around the game map. But,
it's a good start.

+Hypothesis: `MENUTYPE` and `SUBMENUTYPE` are actually distinct lists of values.
+So far, I've been treating them as the same thing, but, e.g., `MainGame.mnu` has
+a `MENUTYPE: 45` which is labelled "MAIN BACKGROUND", while `SUBMENUTYPE: 45`
+is tentatively labelled a "thumb" and used in text boxes. There are also a few
+cases where I've had to manually override the `MENUTYPE` because it coincides
+with `Button`.

 ### `ACTIVE`
 
 There are only 4 values seen across all menus: `0`, `1`, `1,0`, `102` and `1,1`.
