Bug 1014994 - Part 1: Register RemoteTabsPanel. r=margaret

This is the boilerplate to add a new RemoteTabsPanel HomeFragment.  At
the moment, it merely displays a static view with a static string.

The panel title is "Synced Tabs", per yuan's design PDF; and the panel
appears at the front (far left) of the list on phones, and at the
back (far right) of the list on tablets.
