Implementing support for displaying IndianSettlements. Includes changes
throughout code, addition of some images, and addition to protocol.

Beginning work on revising data structures for Tiles, Buildings, and
Settlements, to move away from enum's and if-then chains to use of
linked lists and hashmaps. Additional work is required to fully
implement this change, but this gets our foot in the door.

Beginning work on fleshing out dynamic typing with TileType and
SettlementType. This is somewhat experimental at this stage and will
require further work to fully implement, but again - this gets the foot
in the door so it can get some use-testing.
