PysmurfController: disable "stream" start and re-order other ops

[mhasself]

It is deemed harmful to permit people to start streams, so we'll suppress that ability through ocs-web.

Also, let's reorder the ops in the Right Panel -- e.g. restart_rssi should probably be closer to top and/or have a special button in Left Panel.

After a quick discussion the sort order priority sort is:

Top:

• stream [.stop only]
• restart_rssi
• uxm_relock

Others lower. Also, disable uxm_setup.start.
