Bug #7547 - Cannot log out of WebUI from mobile device

When accessing the Sat6 WebUI from Firefox on Android, no log out link appears, so there's no easy way to log out or sign in as a different user.

Add a user button to fix this.
Cool,  only suggestion is to move this button you added below, right below ```<div class="navbar navbar-default navbar-inner navbar-fixed-top persist-header">```. That way it looks a little neater: ![](http://i.imgur.com/WBd1gWZ.png)
