Initial Newmalf port

- Ports TSA Newmalf code.
- Complete overhaul of Malfunction. New modular abilities, 12 of which are in game by default.
- Adds AI hardware. AI may have only one piece and it gives unique boost in certain area (turrets strength, secondary power supply, etc.)
- Adds hardware drivers - these abilities control AI's hardware such as the APU power supply or self destruct explosives.
- Station overtake was changed to "hack all APCs" ability instead. When completed self-destruct is unlocked. Timer for station self destruct increased to 2 minutes. AI may activate/deactivate the self destruct at will.

Please bear in mind this is only INITIAL COMMIT. More commits are to follow. Minimal player count is now set to 1 but will be 2 when finished.
