Rematch

01/27/2024 version 5.1.1
- Updated the import dialog to allow picking a group the imported team(s) would go to (unless there's any group definitions in the import) first
- Added 'Import Teams' to group right-click menus to import teams into the same group unless the import includes group definitions
- Added 'Delete Teams' to group right-click menus to delete all teams within a group without deleting the group
- Rather than hide the 'Delete Group' menu option from the right-click menu of Favorite Teams and Ungrouped Teams groups, the option is disabled with a tooltip to explain these are system groups that cannot be deleted
