"Merge package"-function: display of elements as tree-view

[JStratil]

In the menu "Merge package" we would suggest a display of the elements to be merged in form of a tree-view:
Annotation types --> individual annotation type --> individual annotations
In this way each annotation could be easily assigned to a specific annotation type. Furthermore one should be able to select individual annotation types to merge/import all annotations of this type with one click.

This has been partially addressed in 1a4ce2d : a Type column shows the element type (annotation type for annotations), and the table can be sorted against this column. Moreover, multiple selection is possible (by holding the Shift key while selecting).
