Creates the "Reset Telecomms Scripts" adminverb

Easy one-click reset of all telecomms scripts.
Fixes #4290
Not if it's called only once.

HOWEVER we do have a list for telecommunications machinery, so you should
use that. (can't remember the name atm, it's used in most tcomms machines
and talk_into)
