Add PreviewDeck controls to keyboard mappings

[jus]

Patch adds the following shortcuts for [PreviewDeck1]

LoadSelectedTrackAndPlay Alt+Return
start_stop Return
back Alt+Left
fwd Alt+Right

Some quirks:
1. As already reported in lp:1114127: Invoking the "LoadSelectedTrackAndPlay" control twice on the same track, does not stops previewing a track. As result, we cant stop previewing a track currently using only one button on a controller/ one keyboard shortcut.
2. Scrolling trough a track in the previedeck is somewhat uncomfortable using the "back" & "fwd" controls. I would prefer to use the "playposition" control for rapid scrolling, but could not find a way to pass values in keyboard mappings .

Anyone tested the updated keyboard mapping?
Any objections this should not slip into 1.11?

I'm fine with any updates to keyboard mappings in 1.11.0.

The shortcuts work well for me. I think enter might be a little confusing since some users might want enter to load the selected track into the first empty deck (equivalent to double-clicking a song in the library).

Fair point, current solution is not really good.
Return = load the selected track into the first empty deck
seems the more obvious choice. The main point for introducing "LoadSelectedTrackAndPlay" was that the PreviewDeck does not need to respect the other decks track load behavior setting. But as said, "LoadSelectedTrackAndPlay" needs two shortcuts to be able to start/stop a track. If we could use the control with only one shortcut, we would free RETURN (or any other other assigned key). Unsure how the logic should look like, since one must check if a track is running to be able to stop. But what if the user wants to load a new track for previewing while a track is still playing in the PreviewDeck?

Or instead of RETURN we simply use an other shortcut for PreviewDeck,start_stop.
Suggestions?
