Deere skin: Formatting
Deere skin: Added a standard knob with an additional pushbutton (e.g. for adding kill buttons next to a knob). Use it to place Mute and Keylock buttons next to the mixers Gain and Pitch knobs.
Deere skin: Remove obsolete additional Mute buttons from the mixer and microphone section. The buttons are placed next to the respective gain knobs.
Deere skin: Move Pitch control below the EQ`s and rename the label from Pitch to Key. This follows the knob order/label found elsewhere. We should not try to set new standard here.

Some appdata.xml fixes.

* Add name/summary.
* Set metadata_license to CC-BY-SA-3.0.
* Set project_license.
* Add screenshot caption.
* Use component rather than application.
Remove unused files.
Fix AutoDJ empty-queue disabling to update the CO and disconnect signals.
Fix race condition in starting AutoDJ

* Better support for multiple decks: switch from loadTrack signal (which has an
  implicit target) to loadTrackToPlayer so we are always explicit about
  what player to load a track into.
* When first loading AutoDJ, use load-and-play signal instead of
  assuming the track is loaded and ready to play when we call play().
* Make the no-deck-playing enable AutoDJ test more complete to show we
  properly transition into ADJ_IDLE mode.
Fix race condition between loading a track and removing it from the
AutoDJ queue. Potential fix for Bug #1206080.
Deere skin:  * Add a stack of beatjump controls that jump forward or backward by X beats. Default is 4 beats. * Add a  stack of loop move controls that move loops forward or backward by x beats. Default is 4 beats.
