Refactoring player view scss
Moving player iframe url to controller entirely

Originally a "youtubeLink' was virtually constructed on the server,
this was than concatenated with the remain iframe youtube parameters
in the template and sent to a trustSrc() method, which would run
it through $sce.trustAsResourceUrl(), for use. This worked about
80% of the time, but 20% of the time it would load a copy of the
site's landing page inside the iframe instead of the video.

By eliminating the virtual model field and relying entirely on the
construction of the link on the client in the controller, this
seems to have corrected this bug.
