Implement variants tags inspector work

Implemented features:
- UI for the variants tags in the inspector.
- adding, renaming, and deleting tags.
- adding, renaming, and deleting tag groups.
- adding, renaming tags/groups is checked for name uniqueness across
  project.
- deleting tags/groups checked for in-use across the project.
- toggling tags state.
- tags are synced with the UIA/UIP.
- changing group color.
- the variants property in saved in the <Graph> part of the UIP.

Remaining tasks:
- implement import and export.
- issue: renaming a selected tag, toggle it unselected till next project
         load.
- issue: update the property after deleting a group that is in-use in the
         property in the currently open doc but not saved.
- thorough test and tweaking.
