Fix hard crash when extra details selected in plot error reporter

Fix sans gui state bugs

Re-calculate duration in split-out workspaces from FilterEvents

Update Error Reporter Unscripted Test

For some reason mantid plot would recurse until segfaulting when the
text entry was selected when it crashed "softly".
Making the edited flag false before maming the edit seems to have
solved the issue.

Add a reminder to test it on Workbench as well as Plot

Fix crash when remove function and closing interface

Fix Interface Opening Exceptions

Revert engineering diffraction removal

Add ISIS-only note to ensure that mantid is updated on the beamline PCs and IDAaaS when appropriate.

Fixes the error states not being set correctly by the SANS GUI whilst
processing

Fixes an incorrectly emitted message when trying to convert an empty
string into a StateShape object

Fixes each row not switching to processed, as the view is not instructed
to update whilst processing

set_aspect in matplotlib 3.1 is removed for 3d plots as it never worked
as expected. Removing for all versions as the function doesn't work
properly anyway and it's stopping the interface opening.

Fix import_qt Causing Failure of Packaged Nightly

Using the import_qt method with the file, rather than the directory, was
causing the a packaged version of mantid workbench not to launch.

Make beam centre results comparible

Fix BeamCentreFinder not running at all

Create plotting figure in overplot if doesn't exist

Replace block-style progress reporter with C-api based one

IN16B minor changes

Change the SANS Beam Centre Finder to prints the average residual change
between two quarters. This allows for direct comparisons, previously if
a user increased the radius limit it would appear to perform worse,
despite actually doing better. This was because the additional number of
points was not accounted for.

Breaks out the main loop of BeamCentreFinder and extracts down the
methods for later. The results before and after were validated to not
have changed.

Fixes up two errors in the beam centre finder:

- The first is an erronous to_string which was introduced with the
conversion to Python enums in PR #27508
- The second is an error with plotting in workbench which has always
existed. A seperate issue is open, however we can work around it in the
mean time for safety.

If a user is trying to overplot, but hasn't created the figure
initially, we now detect and create it for them. This makes overplotting
in a loop trivial from a user's point of view.
