CellCius is now a robust, retrying (with exponential backoff), long running process.

It keeps the session open so you'll only receive an SMS on startup, it then polls
the site (using the existing session) every 9 minutes.

If the sesssion dies (ie. Cell-C reboot their servers?) it will detect the lost
session and recreate it, at which point you will receive another SMS from the
Cell-C site.
