  - LP: #1059127
  - fix longstanding "date and time flash on and off" bug
  - this isn't a great fix, but it's a start
  - basically, we need to use the tmux status native support
    for timestamps
  - support configuration through ~/.byobu/datetime.tmux
  - this will be a difference between byobu-tmux and byobu-screen,
    which is a bummer
  - also, there's more work to be done, in order to enable/disable
    this via F9/byobu-config
* usr/lib/byobu/include/constants: LP: #1278446
  - ensure that we pick a python that has a proper snack module
    installed
