A couple of meter orientation fixes

1)  On startup if the capture meter is vertical and
    the playback meter is horizontal, capture meter
    would jump to horizontal if you start monitoring.

2)  To cut down on meter orientation weirdness, the
    orientation is now mirrored in both meters when
    it changes.

    If this is not a desired behavior then the only
    option would be to have separate config file
    settings for each meter.  That means that the
    orientation settings in meter preferences will
    correspond to that meter only.

    Let me know if this is what is wanted.
