Add Group Policy Preferences support to db_import

And take the Jaden Smith approach, as @busterb quipped to me. :)

This one's a little weird, since you normally import scans into
Metasploit, but now that creds are first-class in the database, it makes
more sense to be able to import them.

Currently, your alternatives are post/windows/gather/credentials/gpp,
which requires a session, and auxiliary/scanner/smb/smb_enum_gpp, which
requires a network scan.
