Add brackets to timestamp when copying if hidden

Add brackets around timestamp if ShowSenderBrackets is disabled -and-
the timestamp format does not contain brackets.  This matches all
common types of brackets using a regular expression.

Remove any leading and trailing space from timestamp format before
copying if above conditions met, to avoid having [ 11:04:32] or some
such.  This might be unexpected, but if someone has specific needs
for the bracket arrangement, they can toggle to always show sender
brackets.

Examples with show sender brackets disabled:
" hh:mm:ss"     -> "[hh:mm:ss]"
" h:mm:ss ap"   -> "[h:mm:ss ap]"
"<hh mm ss"     -> "[<hh mm ss]"
"[hh:mm:ss]"    -> unchanged
"<hh mm ss>"    -> unchanged
"{hh:mm:ss:ss>" -> unchanged (and I won't ask why you're doing this)
