AGM Repair Module

Basic repair module by Hawkeye104.

Creates a module in the 2D Editor that lets you define the following
values:

* TimeRepair
** The time it takes to repair damage to "heavy" components e.g. engine,
body, fuel
* TimeWheelRepair
- The time it takes to replace a wheel
* TimeTrackRepair
- The time it takes to replace a track
* MaxDamageRepair
- Limit the amount of damage that can be repaired on "heavy" components.
0 = all damage. 1 = no damage repaired. I know, it's backwards.

* Adjusted function scripts to accommodate new parameters

* Added repair module script

Future:
Would like to add boolean parameters preventing the repair of heavy
components.
These parameters should have the same current default values. 10 for the times and XX for MaxDamageRepair
