[CHANGED] Uptime Display

These fixes are for the uptime view located here:

index.php?page=statistics&action=uptime

The data coming back from uptimerobot has changed.
The commit: 
* Adds a new 'cloud' icon. This is used for column 0 (replaces flag which is now the test name).
* Removes the colum1 (Service), because if you're  monitoring a port (eg stratum) service gets returned blank
