APCs that are undersupplied now call cell.give()

APCs that are undersupplied now call cell.give() instead of manipulating
cell.charge directly, for better encapsulation.
Corrected comments for CELLRATE and CHARGELEVEL

Comments erroneously stated that a value of 0.002 would convert 1000
watts to 20 charge per tick, when in reality 1000*0.002 = 2 not 20.
Similarly for CHARGELEVEL.
