Split out from  FS#11748 .

This patch adds an option to prevent rewinding to the beginning of a track to avoid losing the current playback and resume position by accidentally pressing the Left key. Instead, Left always directly skips back to the previous track. This behavior can be enabled for all tracks or only for those tracks that can be autoresumed on automatic track change (which already is separately configurable).

I'm dropping this patch here for now because I see little chance right now of this being accepted into the trunk. Some developers have complained about the considerable configuration complexity of autoresume as it is, and although this additional behavior can be convenient, there is no ultimate need for it because the resume position prior to the rewind to 0:00 is preserved as long as another skip occurs within the first 15 seconds of the rewound track's playback (for example, by pressing Left again to skip to the previous track).

This change was originally contributed by Dave Slusher in  FS#11748 . I just added the configuration logic.

Patch relative to r29484.
