[MERGED PR] Destroyable lockers

[aloe]

would probably do 3 tiers- no access/locked/high-sec
Lockers without a lock should be able to break pretty easily, lockers with access restrictions less so, and armory/head lockers can have very solid protection.
If you're doing this you should probably make explosions work on the same system (health)- it's a bit silly that 100 potassium and water explosions might fail to break open a locker when 1 piece of erebite will.
I would also rather projectiles worked to damage them, so traitors who buy guns aren't prevented from busting lockers (this makes the saber into a bit of a locker busting tool, even with the damage maximum). I'll add that in a few days.
I haven't actually gone through the code yet, so I'll probably come back with some Actual Code Feedback later.

edit: would also be cool to have Brokenness Tiers like with doors (kinda) and consoles. Where hitting it when it's < 20% health or something has a chance to bust the lock; could make high damage projectiles do the same thing.

P.S. FUCK large storage pathing. I wanted to go refactor this a while ago and it's just. god
