Fix a handful of msftidy warnings, and XXX SSL

Marked the SSL stuff as something that needs to be resolved in order to
fix a future bug in datastore manipulation. Also, fixed some whitespace
and exec complaints.

Somewhat related to https://dev.metasploit.com/redmine/issues/8498 because of the datastore manipulation, but mostly this is just some release-time fixup.

(@bturner-r7, none of this is critical for you, take it or leave it -- should be landed in master regardless of your designs)
