Tell users when there is no data available in Daily Report

Here is the text from the bug:
If there is no metering data from the period selected,
user sees panel with no tables. It would be nicer to tell user that this is because there is no data to show.

The Daily Report displays one table per project. Since there is no data, then there are no tables.
This change displays the string "No data available" in this situation. This is the same
behavior as the Stats tab in the same Resouce Utilization Panel.

Perform natural sorts on "Hostname" column on the Hypervisors panel

The API calls just return the results in who-knows-what order, so
explicitly sort them so they make sense.  Also tell jquery-tablesorter
how to do natural sorts, so that the results continue to make sense
when the users fidget with them.
