- Renamed signal and assosiated notification methods.
- Added old text as a signal parameter.

Re #22263

Re #22263

- Moved call to enableFiltering into constructor of JobTreeView.
- Exposed the RowLocation operators through SIP by making them member
  functions.
- Should do as above for Row and Cell in later commits.

Re #22263

- Added notifyResetFilter, called whenever the filter is reset by the
  view.
- Renamed borderTransparency to borderOpacity to better reflect the
  fact that a borderTransparency of 0 is fully transparent.
- Reimplemented RegexFilter in a more flexible and consise way.

Re #22263

- Added the aforementioned properties to the Cell class.
- Added mechanics to CellStandardItem functions to extract and apply
  these properties.
- Fixed a bug in RowLocationAdapter whereby rows on the path were
  required to have at least as many columns as the column of the index
  being fetched.
- Exposed this new functionality to python
- Experimented with these properties in batch_widget_gui.py

Re #22263

- Fixed copy-paste border colour problem.
  - Made transparency stored separately from the colour in the Cell class.
- Moved padding functionality into C++ JobTreeView will now pad rows
  shorter than the model column count with 'dead' cells.

Re #22263

- Moved methods for operating on QStandardItem/Cell objects + custom role
  enum to CellStandardItem.h/cpp.
- Increased CellDelegate's awareness of custom roles.
- Changed storage-duration of QtFilterLeafNodes to automatic.
- Used new functionality to perform padding of group rows - this
  functionality should be moved into JobTreeView in a later commit.

Re #22263

- Used QtFilterLeafNodes as a proxy model over the real model.
- Added strongly typed QModelIndexes based on StrictModelIndex template.
- Added methods and refactored code to handle conversions between
  different model index spaces correctly - strict QModelIndex classes
  help to enforce this.
- Refactored QtStandardItemTreeAdapter to be a set of methods rather
  than a class - a different logical grouping may follow.
- Added filterRowsBy methods to set the filter predicate and
  resetFilter method to switch to a true-predicate.
- Exposed this filtering functionality to python.
- Split QtTreeCursorNavigation into additional header QtBasicNavigation.
- Moved RowLocation -> QModelIndex and QModelIndex -> RowLocation
  conversion logic into RowLocationAdapter class to allow re-use in other
  contexts such as QtFilterLeafNodes.

- Added BuildSubtreeTest - a replacement for the messy version in JobTreeView.
- Added additional methods for dealing with Subtree objects.
- Modified interface of the copy and paste signals presenters must now
  get selection explicitly.
- Exposed Row class to python.

Re #22263

For demo purposes.

Re #22263

- Track last edited cell + overload commitData to enable user
  updates to be distinguished from presenter updates and only
  dish out notifications for the former.
- Add copy notification method to JobTreeViewSubscriber interface.
- Add new signal to JobTreeViewSignalAdapter.
- Update SIP bindings.
- Add and expose depth() method on RowLocation.

Re #22263

- Based of dataprocessorinterface.
- Updated build config.
