Mall Cop Sec Uniform Fixes

Fixes the problems pointed out by RobRichards. Thanks!
Adds Baystation's telescopic baton

Feel free not to use this, but I just want it in the code for a future
project. Hope that's ok!
Adds SWAT gear mob sprite

I had this made, but was dumb and forgot to include it. Hopefully this
should fix that.
Fixes Baystation's telescopic baton to work with /tg/station code

Of course, it wouldn't be as simple as copy and paste. I have a terminal
case of the dumb sometimes.
Adds the NT-22 Enforcer police pistol.

What the title says. Reskinned Stechtkin pistol, takes 10mm rounds.
Designed as a projectile weapon for Security that's less powerful than a
shotgun.
Revert "Adds the NT-22 Enforcer police pistol."

This reverts commit 579c944d6fcc0d581c0ece29b8d7b29c65691206.
Adds the NT-22 Enforcer pistol again.

As the title says. I accidentally copy/pasted the code into the wrong
file (projectile.dm instead of pistol.dm), so this re-adds the pistol.
Sorry about that!
