Let black powder open lockers

[backifran]

I just blew both off my arms and a bunch of other stuff up in a large black powder explosion - the lockers were untouched. Please make it so it's possible to open lockers other than an emag or if you're VERY lucky and they survive a bomb blast*

Black powder would do this.

*I've tried this on zeta several times with the RD bomb and I died every time, the lockers were either vaporised or remained frustratingly shut
