Another big change checkin. Highlights:

* Dump the "latest" stamp. Just look back ten days.
* Specify getters. All options default to None. Those which are optional are
  filled in after config file processing.
* Add verbose option. Can be toggled from command line.
* IMAP thread not started by default. Start from command line.
* Peek at message bodies without marking messages read by our actions.
add one, complete one.
