Multiple misnamed variables in bbdb posting styles

lisp:/gnorb-bbdb.el: gnorb-bbdb-configure-posting-styles was a mess of
		     undeclared variables -- bad copy & paste, possibly
		     due to drunkenness.

Mostly `called-interactively-p' with no arg, a few leftover
nnnil-status-strings, and `insert-buffer' replaced with
`insert-buffer-substring'.
