As the diffs for mobile and desktop site converge one of the side effects was the visual diff control now loads in the mobile diff sans the javascript that makes it work.
The visual diff control should check to see if it is in mobile mode (using MobileContext::shouldDisplayMobileView if available) or should integrate itself into the mobile site.
For the time being it is being hidden via hack in MobileFrontend in resources/mobile.special.mobilediff.styles/mobilediff.less.

Acceptance criteria
- The control is either conditionally added or added and works.
- MobileFrontend hack removed
