Support for user-specified minimap bounds

Browse source 
The totally-not-a-secret reason I made this branch.
- doomednum 770 (associated with polyobject anchors 760/761 and skybox centerpoint 780)
- Place exactly two in a map to draw an implicit rectangle.
    - Supports top-left/bottom-right AND bottom-left/top-right placements.
    - I_Errors if you place too many (or only one).
- You don't *have* to have these, this is just a bonus if you're a map like Power Plant or CDSS1 negatively affected by your skybox.
