Add XMOMs to clip board from search results by using the context menu

[gipkai]

Use-Case: Starting from the search results, the user wants to insert one of the XMOM matches to the current workflow. Currently, the user has to open the match, copy the Label into the search field and finally insert the found XMOM in his/her workflow.

Solution suggestion:
The offered context menu should be extended in such as way, that the user can add the found XMOM to the clipboard. (e.g. "Copy to Clipboard" entry). Then, he/she can use the object in the clipboard inside the current modelled workflow. This would speed up modelling substantially.
