Enhancement request: sort by "Hosts" in packages.php

[bluikko]

Currently when listing packages, the output table can be sorted only by "Name" and "Architecture".

It would be useful if the packages could be sorted by "Hosts" also. It could simply sort by the count of hosts per each listed package: a package that is detected on 3 hosts would be listed before a package that is only on 1 host, and packages currently on no hosts would be at the end.
