- Automatically create workspace file in a mapset when GUI is notified about the change if it does not exist.
- If workspace exists in a mapset, open it.
- If workspace does not exists and but the previous mapset was in the same location, it keeps the open mapdisplays as before.
- The updates to workspace are not saved automatically (in time interval, before switch, or at exit), so user needs to save the workspace (Ctrl+S) in order to keep the state.

This is a proof of concept and not meant for merging. If someone wants to pick it up, I'm more than fine with that.
