Lots and lots of goodies

Animated minimap stuffs, as well as some fixes
Fixed minimap bug

Fixed minimap bug involving the focused room not properly being shifted
over with centerCorrect(), causing trackers to work weirdly.
Fixed another minimap bug

Fixed bug where the linked minimap wouldn't update its lighted path
properly, leaving a ghost path behind until the PC moved.
Fixed a tooltip bug

Fixed a bug with tooltips where a "ghost" minimaproom would still have a
tooltip show up.
Added exploration support

Now, many rooms don't just start out on the map, you have to explore
them to find them.

Also a bunch of fixes to minimap stuff.
Updated tarkus blow up to use new system

Hard to test, though... I don't even know if I've ever even done it
before.
