Security starts with a baton

My last request included the .dme, so I removed it from this request.

"Spawn Sec Officers with a Stun Baton - RECEPTION: LIKELY TO BE ADDED
Remove the Batons from the Departmental Offices if need be, a Flash is a pathetic non-lethal tool to use as many items can block it and late joining Officers might quickly need some heavier application of force if they are caught by surprise."

Files Modified:
code/WorkInProgress/Sigyn/Department Sec/jobs.dm
-It appears that this file is for when security officers are assigned to a department. If the player has a backpack, the modification adds a charged stun baton to it. If not, it does nothing.

code/game/jobs/job/security.dm
-This appears to be the file for when security joins late-game. The modifications do the exact same thing as the previous file.

    code/game/objects/structures/crates_lockers/closets/secure/security.dm
-This file stores data about secure closets, id est the ones in security offices. I removed the stun batons from those, because security officers will now start with them.
