Laser Scalpels Ver. 1

Adds four new researchable surgery tools - three laser scalpels with improving reliability as they are upgraded, and an incision management system.

The laser scalpels combine the steps of incision and clamping bleeders, while the incision management system adds the third step of opening the incision with a retractor.  This saves time in the OR.  These devices act as standard scalpels for the surgeries without the clamp/open steps - facial reconstruction, eye repair, debraining ...

Thanks to Pawn for the sprites.  On/off states exist for power tracking and the ilk, should it be desired.
