[George Staikos]

CVS commit by staikos: 

1) I somehow reverted my fix, so restore it: must add to existing plots before
   adding new ones otherwise the combobox gets desynced.
2) rework the plugin handling a bit - should work better now
3) don't allow vectors/scalars to be created with existing labels
4) vectors/scalars created with blank tag get one automatically assigned.
