Plugins » virt-who configure

Few issues:
1. The title `Virt-who Configurations Statistics` should be called `Virt-who Configuration Status`
2. The title `Out of Date Virt-who Configurations` should be called `Latest Out of Date Configurations`
3. Both the above titles should be left aligned vs. current center aligned
4. The first column name of the Table can be called `Configuration Status` instead of `Status`
5. The line items can be named `No Reports`, `Out of Date`, `Up To Date` instead of current long names
6. For the second section, The text `No configuration for which the report has not been received during expected interval` can be `No configurations found.`

By making these changes, the virt-who widget will look similar and blend in with other widgets.
