WinGui: Refactored the Encode Service to move any reusable code into a base class. Added a new service which will eventually work with libhb to do encodes. Currently this just contains placeholders which throw NotImplementedExceptions.
Removed the Total Elapsed Time on the Queue window since it doesn't work. This will be re-implemented later.
