*Implements list preferences where applicable to simplify the settings
*Add the ability to track Upstream, Downstream, or both
*Add the option to change the frequency with which it updates

PS6: Update strings and check if stats are supported automatically

Base: https://gerrit.omnirom.org/#/c/5129/

PS8
