power: Minor updates

- Change term 'reboot' to 'restart' as it is less techinical and more
  consistent with popular interaces on desktop/mobiles.

- Updated description for power module.

- Simplify the module title to just 'Power'.

- Update the use of elipses and angular quotes as angular quotes and
  elipses are both used to indicate that further user interface will be
  available after pressing the button.

- Remove suprious '\' in power_reboot.html.

- Notify to the user that web interface will not be available after
  reboot/shutdown.

- Redirect the user to application page after restart/shutdown.  If the
  page serve succeeds, they will have simply refresh/access it after
  restart/shutdown after waiting or powering on.
