Search for all library usages

[franzlst]

Use Case:

In common IDEs the user can search for the usages of functions. This would also be nice for libraries in RAFCON.

Based on this, the user could replace the occurrence of one library with another library having the same interface, i.e. input and output ports. => separate issue

Technical TODOs:

• create a new widget in which the search results can be visualized; therefore create a new tab in the left sidebar (or in bottom bar)
• create a new entry in the right-click-menu of a library state to search for usages
• order the elements in the results widget in a tree-view
• all the leaf-elements of the results tree-view should have the same right-click-menu as the library in the LibraryManager tab (in the left sidebar)
