Add ability to reduce live data via ORNL SANS/DGS/Reflectometry gui

[Russell Taylor]

The idea is to add a 'live' button that will execute essentially the same reduction as in the offline case, taking applicable options from the gui tabs.

This work will initially take place on a branch.

Re #5896. Add a live button to the gui and some early plumbing.

The live reduction to run is hardcoded for now, but is in the right place such that different instruments can kick off different reductions (for now, pressing the live button when not in the EQSANS environment will raise and error).

It ain't gonna happen on the timescale given for this patch release.

Re #5896. First try at adding a live button to the DGS reduction GUI.

Uses some nasty tricks at the moment, which should go away as things are generalised for this to be a feature of the whole reduction framework.

I'm going to do things a different way.

Re #5896. Don't expose to python things that can be set via properties

For things that have been declared via Q_PROPERTY on the C++ side, we can use setProperty to set them and keep the number of methods explicitly exposed to python to a minimum.

Re #5896. A mechanism to change settings when live button is pressed.

Some settings are not applicable or need to have certain values for live reduction. This allows other settings (even in different tabs) to be set or disabled when the live button is pressed.

Re #5896. Fix certain settings in DGS gui when live button pressed.

This fixes the values of certain aspects and disables the gui elements when the live button is depressed. Any changed settings are remembered and reverted when the button is unchecked.

Re #5896. Ensure signal is emitted if state changed programatically.

Switch to a signal that is emitted whenever the state of the button changes, not just when it is manually clicked. This ensures that items are properly disabled if the live button starts out checked. It appears to have no negative effect on the Step Scan GUI (which is the other place listening to that signal).

Re #5896. Check if default instrument same as GUI instrument.

Unfortunately, because the GUI framework uses it's own setting for what instrument it's dealing with, the live button can only be available if that matches the user's default instrument (as that's the one MWRunFiles checks for).

Re #5896. Use user-supplied workspace name for output.

Also put in code to get around the problem that only the first live chunk will have an entry in the EnergyRequest log. For subsequent chunks we have to copy it from the processed workspace.

This code will need cleaning up later. Probably some will be pushed up to a higher layer and perhaps the output workspace can go in the GeneralSettings so that we don't have to go fishing for it.

Although the mechanism has been put into the GUI framework, only the DGS GUI has had a live button added thus far (as only HYSPEC & SEQUOIA have ADARA).

Michael or Andrei should test this ticket as they intimately know their way around this GUI. You'll need to be on a machine that can 'see' the HYSPEC and/or SEQUOIA live streams. You also have to have your default instrument set to the one you're working with.

Merge remote-tracking branch 'origin/feature/5896_reduction_gui_live_again'

[Andrei Savici]

It should be tested again next week, when there is beam. I was not able to test that it reads the incident energy guess from the live stream
