be able to control switches and able to kick out connection
- kickout buttons and switch buttons are now visible to everyone.
- clicking buttons without correct permission will return proper error msg.
Initial implementation.
- added some code in phone_home_stat to retrieve latest version from stat server
and store result in db
- created new view helper VersionNotify.php, which queries and calculates version
difference, then returns the necessary information in html to the view files
- created new javascript file versiontooltip.js, which sets up the qtip stuff so that
when the version notification icon is clicked, a tooltip is displayed
