re: #28415

Creates new tab names correctly on non-GNOME enrionvments for Ubuntu.
KDE automatically binds keyboard shortcuts, which Qt represents with &x
(where x is the shortcut). This breaks the name lookup as &New != New in
"New Tab".

We now strip out these characters when looking up the names fixing the
names not incrementing correctly.

Clicking restore-defaults on an Experiment or Instrument tab in a batch should only affect that tab and batch. This commit fixes a bug where a notification was sent to all batches, and every Experiment and Instrument tab was being reset. The fix is to separate updating the instrument (which is required to ensure we have up-to-date settings loaded from the instrument) from the subsequent notification which updates all batches. Instead, the particular Experiment/Instrument tab where the request was made restores its own defaults itself.

Re #28429

The problem here was that when the instrument is set on the new batch, a notification is sent that the instrument has changed and all batches were being reset. However, although the instrument has been set, we can just check whether it is different to the current instrument to check whether it really has changed, and if not, do not do the updates.

While the primary use of the new attenuation profile file feature is expected
to be via the sample environment xml file, it also makes sense to add it into
any algorithms where the material properties can be specified. So I've added a
new attenuation profile parameter to the SetSampleMaterial and LoadSampleEnvironment
algorithms. The validations on these algorithms means they can't be called using
postional arguments so have inserted the new parameter in the logical place next
to the absorption cross section

Have updated the docs to explain how the attenuation profile file is used

Change absolute to absorption in comment against cross section types
Clarify formula in Materials concept page

First checking, more to save state over the weekend

Also updated class_maker.py

They have low to zero usage and at this point are
just a maintenance burden. They do not work in
workbench and are not worth the effort to port.
In the future it would be better to replace input
in workbench with a function that raises a generic
QInputDialog.

This includes docs for ThermalNeutronBk2BkExpAlpha, ThermalNeutronBk2BkExpBeta, ThermalNeutronBk2BkExpSigma and ThermalNeutronDtoTOFFunction
