refactor, pentatonic, jeb, getopt

Add a PentatonicParty, which is a party that plays pentatonic notes as
music.

Broke API by changing format of -g flag.

Use a Java port of GNU Getopt for command parsing.

Overhaul guests in code to be whitelist instead of blacklist; current
guest list works without issue.

Remove broken disco floor code.
