Implements Top Talkers and Top Applications In Time Range

Browse source 
Top Talkers and Top applications can be retrieved via MySQL
both interface-wide and per-host. A couple of tabs, namely
"Top Talkers" and "Top Applications" become available in the
historical page of interfaces and hosts. Upon focus of each
tab, an ajax request is triggered and data is fetched from MySQL.

TODO: interface wide top-talkers are retrieved from sqlite and
need to be moved to mysql.
