RCP: 0.7.8: re-use corpus description editors with Description command
Currently when a corpus or sub-corpus Description is called, a new editor window is opened. It would help the user to re-use description windows related to the same objects instead of multiplying them.
Solution
When a Description command needs to open a window named “XXX”, re-use any already existing window named “XXX” instead of creating a new one.
