Voicemail: Add delete and move functions

Refactor some of the list handlers becuase delete and move have to act on
multiple files.  Also make it so that any played messages in INBOX
automatically move to Old.

To get the MWI to work, you have to set

pollmailboxes=yes
pollfreq=5

In voicemail.conf because we're now tampering with the files outside of the
application.
