Project Save: Plots should dynamically fill tick properties based on if values are present

Update release notes for v6.1

Update VersionNumber.cmake

Prevent code completions from generating errors

Remove instances of AlignDetectors from ISIS powder scripts

Muon Analysis Fix Crash When Loading PSI Data In Co-Add Mode

Fix bad calculation in PEARLTransVoigt function

If we cannot generate a valid completion list then we should
just stay silent and not show errors

There are some calls to the deprecated AlignDetectors in the ISIS powder
scripts (in the calibration methods) that I'd not noticed when originally
moving the AlignDetectors functionality into ConvertUnits
Swap these for "ApplyDiffCal + ConvertUnits + ApplyDiffCal" to avoid users
getting a message saying there was an error (the deprecation warning) while
running a calibration

Remove instrument viewer warning on cylindrical views

Update MSlice.py

Previously only the base filename was passed, meaning mantid would start searching in user directories rather that just using the file the user specified

* Import Qt before mantid in docs build

The comment in the code explains the issue
in more detail

* Fix case of word in option docs

The comment in the code explains the issue
in more detail

When viewing instruments that have banks that are width "one detector"
in x or y or z, the instrument viewer was giving a warning about "failed
to build unwrapped surface" when you viewed in one of the cylindrical
projections. Remove the warning and also the code to assign values to
u_min and u_max shortly after. The pre-existing values of 0 and 0 are
fine for these values which are in radians
Also include some line length changes that come from the latest clang
format version

Changed SHA for MSlice

Muon ALC - Fix crash when changing to linear plot scale

Minor changes to CalculateMultipleScattering algorithm

list q values as q elastic on reduced ws

* Implement threading similar to project recovery for memory widget

* Improve mainwindow closeEvent and clean up test threads properly

* Remove old test in Cmake

* Ensure updates are cancelled and not restarted

* Make the memorypresenter more generic

* increase stability of tests

* Implement review feedback

* Remove unstable tests

* Reintroduce now stable test and utilise separate threaded methods

* Stability improvement

* Further test stability improvements

* Use a more specific time to wait to ensure that the value is set

* Memory presenter test stability
