Changed Advanced Battery Box gui to be more intuitive
When input/output is disabled, disable button and don't show that side
Changed battery box modes over to an enum, and made external plugs go away if set to quantum (though still connects to wire)
Changed BUILDCRAFT in the new enum over to PNEUMATIC. Made input/output direction variables clearer
Made placing batteries in work when said port is disabled
Fixed (I think) unlimited power generation using two battery boxes.
UE wires should probably detect neighbor change better. Only works if
neighbor being changed is another wire (which an advanced battery box is
not)
Lots of changes to the advanced battery and its gui
1) Made off be an X instead of an empty square
2) Made a more graphical (and I hope intuitive enough) way of selecting
input and output sides
3) Put the faint image of a quantum link card in its slot
4) Refactored its code a bit. Direction code now mirrors mode code
Reverted some local changes to build.xml that were accidentally committed
