Started working on display in map.

9:00 though, so I gotta chince.
Created a MapDisplay
Made the InventoryDisplay a Display

Beyond being a little simpler, this gets a step towards having that guy
slide on
Added a DataDisplay to the MapView
Cheezy, sleazy easing in for InventoryDisplay
A base ControlPanel class + HexControlPanel
Expanding HexView to accomodate ControlPanel
Also expanding MapDisplay for ControlPanel
