-Cleaned up sacrificing again so it didn't rely on hasvar()

-Made a variation of hasvar(), creatively named has_var(), intended for objects versus datums, and the var name is case sensitive
-Clean up mech fabricator code considerably, the terrible switches are all gone, and I was able to make it more robust at the same time. Now, if a junk item is added to the mech fab then it will remove it in 1 of 2 places, either when you call for the queue to be displayed (Will throw it out then rebuild the queue) or when it is processing the queue (Will throw it out then reprocess the building), so now you won't even see the shit that finds its way in there.
-Made the add_part_to_set() useful, now instead of dumping everything in the "Exosuit Equipment" category, it checks if the design's category matches one of the part sets, then adds it to said set if it does (All others get dumped into "Misc"). Right now there isn't much through, mostly just moving MMIs, cells, etc... to the "Misc" set, but this would be easy to use with any other system that handles designs
-Little bit of OCD here, but I noticed that the cells on the map were all 'crap' cells, even though they had 1.5x the charge of a high-capacity cell, so I changed them all to high-capacity cells with the added capacity
