Added a button to toggle the display of archived tracks in TCP. It is useful to quickly see all archived tracks and be able to select them to unarchive. Then click on the button again to return to display tracks as it was before.
Also a command in Tags menu to delete all tags in the project. To start fresh if needed to import another set of tags, etc..
