Remote changes

It would be nice for some remote updates. All are things the Live TV/DVR app Channels does, so I’m stealing from them:

Siri Remote:
Double click on left or right side of the trackpad to skip forward or skip back in videos with chapters.

Harmony Remote (or external remotes in general):
Left button to jump backwards 10 seconds (or could be configured in settings to something else like 7 or 30)
Hold left button to seek backwards (like current) but add when lifted play from that point
Right button to jump forward 30 seconds (or could be configured in settings to something else like 10)
Hold right button to seek forward (like current) but add when lifted play from that point

Better support for the remote would still be awesome, so chapter support would actually be beneficial on movies and the chapters I put to skip commercials when I record with my HDHomeRun.
