Fixed PDA messaging.

Fixed PDA flashlight.
To clarify, you can still use the PDA when you are stunned/weakened. This was always the case, apparently. You cannot use the PDA when knocked out or dead.
You can now stick an ID card into a PDA without clicking 400 times (click on PDA with card in hand).

Changed how the ninja suit functions in relation to energy. It will now hold a power cell as APCs/Borgs/etc.
Ninjas can now replace their starting power cell (reduced to high capacity/10000) with larger capacities. Drain the cell as normal to do it. On that note, hyper-capacity (30k) cells added to research.
Can now drain energy from a recharger. Much like draining from wire.
Added cooldown to certain ninja abilities. It is a global cooldown; meaning, most abilities will be unusable until it finishes. Usually a second.
Some icon changes for ninjas.
