[qt-components] Expose a gconf key for framebuffer orientation in MDeclarativeScreen

directly through a new property of MDeclarativeScreen, but it should
be used for more logic in later work.

[qt-components] Remove FeedbackPlayer.

This uses the (closed source) mfeedbackd, so it's rather pointless keeping this
around.
