1. changed the behavior so that the tooltip comes up on hover
2. changed stat server link to "http://stat.sourcefabric.org/airtime_latest_version"
3. only updates the db if version returned by stat server is valid
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
-default created stor dir now has www-data:www-data permission
-created airtime-install.ini file for specifying install defaults
-removed all references to storDir in /etc/airtime/airtime.conf,
and get value from database instead.
