~/.bin/run: Run and observe commands in the background

This uses `nq` and `notify-send` to run commands in the background,
collect their output, and notify the user when they're done.

This allows running long-running jobs in the background, without loosing
their output, and with notifications when they're done.  This can be
used to download videos in the background, for example.

This is the first try, but it's already useful.
