Hardsuit Mark Two, more Hulabaloo

Adds all sprites for the nukeop and research hardsuit. Shuffles around
hardsuit spawns and gear so they make sense, especially for the ERT,
they still only have two hardsuits per department, but there are enough
magboots and vests for the people who need the regular armor. Added the
medical hardsuit and its attendant gear to the station hardsuit list.
Added all of the xenoarch gear to the hazmat hardsuit for Zuh. Moves
some suit storage things around as they were lost somewhere along the
way since I committed them. Moves the Hazard Suit custom item over to
hardsuit code to prep for them being buildable on station at some point.
For now has the same stats as a voidsuit, no modules, just drains power
and has some extra pretty sprites. Sending this over to dev freeze
because most of it is required for hardsuits to be nice and pretty for
master. Now compatible with latest fixes.
