CuteTube-QML - YouTube client rewritten, and now with upload

CuteTube, Stuart Howarth's YouTube front-end, has been given a Qt Quick makeover: The main additional features of this version are the ability to upload videos. Another change is that video playback is performed using either Media Player or KMPlayer. Features missing from this release include sharing via twitter and facebook. These features are on my TODO list. The new version, which can live alongside its earlier sibling, is in Extras-testing as "qmltube". Those willing to test and rate it against the QA criteria are encouraged to do so.
