Title: Use NSSet for GPGOptions domainKeys

Profiling showed that the previous string-search implementation of GPGOptions domainForKey:
was a bit of a drag, surprisingly showing up in top-ten functions in GPGMail using up 6% of user methods' running time.

Using NSSet drops it to 0.0%.

I used Perl to alter it, so there are no typos; and it's covered by a couple of unit tests.
