Code: Looks good, and the plugin at work.

Testing with startup: Scope on map, good Scope on image is draggable, good. Noticed som wierd behavior when draggin an dropping the same multiple times:

* wierd snapping to point way out of place, with minimum movment and zoomed inn

* somtimes a wired snap back towards where it is dragged from.

* after moving the scope it broke the zooming (on image) after a misplacment of the scope outside of image.

Need further testing and improvment before going to dev.

To fix this zoom needs to be applied on the position of the tempmarker. Working on that now
