Review request for marble.


Summary
-------

- Default input handler reacts to double click and zooms in (centering the mouse position)
- Introduces the GeoDataLookAt object as a possibility to change the camera view (observer) in MarbleMap and MarbleWidget
- Adds FlyToMode enum to generalize the existing Jump animation
- Extends existing Jump to support source and target with different altitudes. Altitude changed according to travel distance to avoid very high jumps when only moving a short distance
- Adds Linear interpolation as another animation
- Adds flyTo methods to change camera view point
- Adds FlyToMode parameter to existing zoom/pan actions. Those already having a bool animate are unchanged and set FlyToMode=Automatic/Instant internally
- Some cleanup here and there

Testing
-------

KDE and Qt Version, both with animations enabled and disabled.

Expected behavior:
  In non-animated mode: As before, except that double click centers on the mouse position and zooms in.
  In animated mode:
    - Linear animation for wheel zoom actions
    - Jump animation for double click
    - Jump animation when moving to a target not visible on the screen yet
    - Linear animation when moving to a target visible on the screen at the same height
    - Jump animation when moving to a target visible on the screen at a different height (except wheel zoom)
    - Control box zoom and pan buttons as well as keyboard events for zooming and panning are animated
    - Jump animations for "go home" and places selected (unless visible on screen and at the same height, see above)


Thanks,

Dennis
