Bug 1107940 - Remove unused partials from the repo

This fixes Bugzilla bug [1107940](https://bugzilla.mozilla.org/show_bug.cgi?id=1107940).

This removes what I believe to be two unused partials from the repo. It would be helpful if in review a double check could be done, just for a second opinion before it's merged.

I've run a local branch and the platform appears to be behaving correctly without them.

We may want also consider removing the unused` thSettingsPanel` partial and its controller. I guess it depends if we still intend to have a Settings panel. I'll mention that in the bug thread in case someone wants that included.

Tested on Windows:
FF Release **33.1.1**
Chrome Latest Release **39.0.2171.71 m**

Adding @camd and/or @maurodoglio for review.
