Drag'n'Drop to Cut/Copy and Paste into other or same HierarchyState

[franzlst]

This is may a minor feature but useful as it is frequently used in Matlab-Simulink.

Short-Cuts also could be chosen similar to Matlab-Simulink (maybe instate of strg-key the alt-key). Therefore we have to hold the the alt-key free for this feature.

• copy/paste -> Drag'n'Drop with left-mouse-click and alt-key holded
• cut/paste -> Drag'n'Drop with middle-mouse-click and alt-key holded (not used in Matlab but can be helpful to move states from hierarchical level to another)
