task/us173-ta173 -- Group the send_email and send_sms statuses to
trigger failed notifications

top/comms.py
* refactor all references to the move_file() function to use the new
  "err" attribute that manages the error red file condition
* new method group_comms_failures() that checks for a grouping of failed
  comms messages resolves if a given comms events file has a
  corresponding failed facility already present in the comms directory
* modified the process() method to incorporate the new
  group_comms_failures() method

top/templates/err_html.t
* altered the template message to be consistent with the new grouping of
  failed comms notifications
