-Restored power cell sprites to the "V2" sprites as I called them.
-Disabled base and virgo power cell/device/power_cell_research files and moved them into chomp modularity folder instead.
Added to the protolathe (I hope because I forgot to last time):
-Giga device cells
-Giga large cells
-Rechargeable weapon cell
-EMP-proof device cell
-EMP-proof weapon device cell
-Potato device cell
All the giga and recharging cells will require precursor tech 1.
