6/2 post-update hotfixes and changes

- gar/garb/s-gar inhands have been pruned slightly to be more efficient and space-saving because most of them are only a pixel different
- butterfly knife inhand removed, uses switchblade inhand because they're nearly identical and the butterfly is never used
- ion rifle inhand fixed
- telebaton changes, it no longer fits in backpacks when it's 'on' and it also has a slightly shorter weaken time because it basically works as a 100% disarm shove right now
- large clothing placement overhaul, moving around a lot of the clothing, especially in sec lockers, and making a lot of colored jumpsuits probability -- you never know what you might get in a mixed locker! (they'll be a lot less bloated now)
- fixed sec jumpsuit rolldown finally (it's actually an issue with armbands i think but this will solve 99% of problems, sorry security jumpsuit rollers, the sprites will remain in the uniform.dm)
- sec officers spawn with a corporate poster in their lockers, warden gets 3, out-propaganda the enemy!
- military jacket no longer has the SUSPICIOUSLY SLAVIC FLAG looking patch on the breast, armpatches look more like NT logos, comes in the sec officer alt wardrobe with cargo pants on a prob
- STERILE MASKS CONCEAL YOUR IDENTITY WITHOUT ID LIKE BANDANAS, YOU TOO CAN BE IN A JAPANESE YAKUZA GANG!
- leather jackets have a small chance to spawn in black wardrobes and casual lockers, but are still poppin-collar #rare and a decent reward for good botanists who have the time to make them
