Adding tags to applications in kmenuedit which are shown as prefix in the window title

Workflow:
1. Add new application launcher with kmenuedit
2. Specify an application tag
3. As application launches the tag prefixes the window title and eliminates/replaces the window index for multiple similar windows if tag is present.
4. Add specific rules for the window by regex title matching ^tag: .*$

The results are more versatile window behaviors on multiple screens with several different tasks on several virtual desktops and activities.
