ModelEditor: Add new button to open parent diagram

If the currently open diagram has a parent diagram (that is: a diagram
in the package one hierarchy step up) it can now be opened by pressing a
button in the toolbar. Default short cut is Ctrl+Shift+P.

This change completes the navigation features.
