Qmldesktop



Hi
As I worked for a while to provide new desktop UI based on QML there is my first version that I consider as good point to start next versions of implementation with more features currently present in gpodder GTK UI.
At the moment main things that are done:
* most windows prototypes as QML components
* adding podcasts (from podcast directory)
* downloading/playing episodes
* code was refactored to share desktop and mobile common qml code

There is qmldesktop branch rebased onto master. It works for me.
