Added eye surgery as a start to the surgical procedures.

Performed by targeting eyes while patient is on an operating table.
Steps are scalpel > retractor > hemostat > cautery.
These steps will change in the future, when surgery becomes a little more complicated. 
Really this is just an excuse for me to make the operating room which will follow this update shortly.

Included sterilizine, which is going to be part of future surgical updates.

Also fixed that thing where all the tools were named the same.

Changed a sprite that isn't in use yet for surgery
