Sechailer mask (now finished)

Okay this is now finished, I'm assuming the lack of comments in the WIP pull request meant the code was fine.

Here are the notes from the latest commits: 
------------------------------------------------------------------------
-Replaced the Oggs with higher quality ones, they were hard to hear in game
-Reorganised the groupings of phrases from 2 groups to three (good cop, bad cop, and shitcurity)
-Expanded the restrictor, user can now select an option to only play the good cop phrases. Also added a 'secret' way to make the mask only play shitcurity phrases

Added the finished sprites (Credit goes to Iatots for the sprites, though I did some tweaks)

Added the masks to the lockers:
-HoS has a choice between command Blue, and White
-Warden has Red
-Officers have black
-Detective, HoP, and Captain get fuck all

Moved security belts higher up the stack, having to shift through the stuff I'd end up putting in my belt all the time was just annoying.

Changed the black mask's eye covers to green, it just looked weird
