Gang gun adjustments

[TDHooligan]

About the PR

Fixes quirks with the lo-point. Brings up the other pistols a bit to be somewhat consistent in their damage potential.
Striker/revolver do stamina damage, as they're lacking real oomph despite their high damage
Revolver gets a slightly weaker AP effect, as it's currently a little wimpy vs a fully geared gang member.

Birdshot holds its' damage for longer - spread causes missed shots anyway.

Why's this needed?

Bring the pistols more in line with each other. Make the striker birdshot a bit more reliable.

eh, not sure I like giving stun to the pistols like that, especially to that degree - note that a basic taser is 20 stun, and you're putting an AP revolver bullet at 15, in addition to damage

oh, i blasted a dummy w/ the revolver and it did like 60 STA. which is 2/3rds of a revolver magazine to down. i figured it wasn't criminal, as:

• it has no disorient/stagger
• ammunition is rare (a duffel bag drop will net you 6 + 6 spare bullets)
• unintended, possibly helpful effect of making you fall over halfway through a fan-the-hammer attack.
• lowest net damage of all the handguns
  could probably roll it back some, though.
