Merge branch 'atmo-325' into gunnr
ATMO-297 Feature complete

Created new instance service, redeploy_init, that calls
atmo_init_full with a new flag, --redeploy.  the function is called
on 'resize_confirm', 'start', and 'restart'. And will mount ephem.
to /home, as well as start vncserver and shellinaboxd

rewrote the function for deploy_chain so that its more straight-forward..
vnc install and shellinaboxd-install no longer starts atmo_init_full,
new function in atmo_init_full to launch shellinaboxd and vncserver.
