command: make options writeable in idle mode

Until now, options could be accessed as properties via "options/name",
but the access was read-only. Change it so that write access is possible
in --idle mode. (All options have to support setting options at that
time, simply because of the way MPlayer designed per-file options.
During playback, normal properties take care of changing things,
including things backed by options.)

This is work in progress. There are some issues: at least setting the
"vf" and "af" options won't work for strange reasons.
