+added in debris + clear space button
+when a unit is KILLED it is replaced with debris
+decided to only make it possible to clear debris, since accidentally
hitting the button could be very frustrating
+Debris takes one turn to clear, essentially when told to clear debris,
it starts it's countdown to attack, but since it does no damage it
doesn't actually attack, it just removes the debris.

+units automatically charge after being deployed
Got it to display number of credits, can actually spend credits, and
stat table displays when a unit on the board is selected. We still need
to display players bases/supply depots, and a way to damage them. Also
need to be able to upgrade silo. Finally, we need to have the UNIT IN
POOL that is selected display, preferably with priority over the units
on the board.
