Yes, although I don't see a need for this for the moment. We should avoid
this dependency unless we really need to (maybe it could be useful for the
3D landscape plugin)

I agree, we now really need to re-code the whole GUI in QML, and replace
the script engine (I didn't check but I don't think this will be a big
trouble). It will be a good opportunity to fix several design flaws:
- cleanly separate the GUI from the C++ code:
- ideally the GUI should only use the script API instead of doing
direct C++ calls
- could allow to completely control stellarium with the GUI running on
a remote computer (a much requested feature for planetarium people)
- move the movement/click logic in the GUI code as much as possible
- allow plugins to inject their own GUI in the program in a clean way
- allow for 100% QML plugins
- in term of look and feel:
- improve objects search
- display nicer information about selected objects
- improve time navigation
