When a new group is added, that group will automatically be selected and focused.

Updated changelog to reflect updates.

Added new option to the "Group Options" in the GroupDialog to allow the creation of a group that contains the currently selected entries. If there are no entries selected, this option is disabled. If there is more than one entry selected, this option is selected by default.

Fixes failed unit test (keyValueShouldBeEqualForEnglishPropertiesMessages) and style test ( '(' is preceded with whitespace.)

Created the 'Create group from Seletion' item for the right-click menu and a new item on the menu. Began refactoring GroupDialogView, GroupDialogViewModel and GroupTreeViewModel to allow for creating a DialogView that automatically prioritizes 'Current selection'.

Attempted to implement right-click-to-add functionality to the codebase. This ran into several problems and a few Gordian knots which I was attempting, and failing, to untie.

This work included using a standardized SimpleCommand to launch the GroupDialogView each time, and accessed the parameters for that through the StateManager. To ensuring this was doable, however, required changing StateManager from tracking GroupNodeViewModels to tracking GroupTreeNodes. Something in this process broke the way that re-renders occur, and now I am facing persistent issues of:
- Group numbers not updating when groups are added
- Colors on entries not accurately reflecting the groups they are part of

Added functionality to allow users to right click to make a new group from the selection. Updated all group creation and group editing to use the CreateGroupAction class, extending SimpleCommand so it would work with the right-click menu.

Getting this functionality extracted into an Action that could be called with the available states stored in stateManager required some pretty large changes and bug fixes related to synchronizing the various lists of active and selected entries.

Additionally, fixed a bug where when new entries were dropped into a list, the displayed number of entries did not update.

Revered changes to context menu on the main table.

Removed 'Current selection' radio button in `GroupDialog` and replaced with a 'Include currently selected entries' checkbox, liked both to a parameter in `GroupDialogViewModel` and a preference added to `GroupPreferences`.

Edited preference menu to include this new preference.

Streamlined `CreateGroupAction` to better fit these changes.

Fixed bug where dragging new empty article entries into a new group wouldn't increment the group count.
