Merge pull request #34 from SickragePVR/feature/FluidUI

Improve UI to display fluidly on different screen sizes.
Revert "Added gui for IMDB watchlists in Config General."

The main core of this code was lifted from Trakt code and not developed enough to be suitable for purpose given that the Trakt code isn't fully developed either. An issue found leading to this decision was that show statuses were set false instead of the expected default, however, worse was that users had no way of choosing shows to add, was not informed of what was actually going on once a URL was added to the UI, and was not offered options prior to adding shows like the normal add new show work-flow does. Basically, there are too many issues and this feature is too immature for inclusion.
