.45 autorevolver

With thanks to TheNineRings for pointing me to these.  Gonna go ahead
and start on the firearms-modernization.
12g pump gun

Like a Neostead.  But Different.
Strikes unnecessary bursting

No burst count, no flag.
.45 lever-action

This one is a cross between the Syndicate Long Range Rifle and the
Winchester lever-actions.  Open to notice & comment more so on this than
usual.
Tweaks

Adds an Ad and tweaks some numbers on the Long Ranger.
Home Frontier Starter Pack

Because in these days of Communist infiltration, Communist subversion,
and Communist indoctrination, *everywhere* is the frontier against the
International Communist Conspiracy.
Spawngroups & modernization

Changed the rifle's designation to comply with Leadworks item ids
(l_name_caliber) and started modernizing DDA firearms.

(There is much more to be done, but doing it all in one shot will likely
alienate the CoD gun fans.)

Full spawngroup list posted as a comment.
Batteries ARE included

Good to know--in the debug menu they come by packs.
