[Transmogrification] Add option to disable when in combat

[pwatts6060]

This issue is for the external plugin: transmogrification
Add a configuration option to show normal equipment when in combat. Some people might like to see their proper gear when doing last man standing or bosses that involve switching so they see they are wearing right gear. That way people don’t need to turn on and off the transmogrification manually. ``

p sure LMS is a PvP area, so transmog should be off there.

but not a bad idea overall
