Applies Icon Caching to battery racks

Browse Source 
In my tests a while ago, I found that the battery racks came quite high in the profiler. So I decided to see if I could alleviate some of that trouble.

Very simple, caches the icons based off of previous work done on the APC, requires less processing for the icon updates.
Function has been tested and has been used on a live server for a few weeks prior to said server's shutdown.
Will make a 2nd PR following another like this except for HUD icons.
