Title: enable actionbar buttons without graphview being focused

There are several actionbar buttons which also work fine without the
graphview being focused (e.g. when a code editor currently has focus). Its
those buttons which don't depend on any selection in the graph view.

Therefore always enable those buttons, as that saves the user one click for focusing the graph view:
* refresh
* save screenshot
* toggle link with editor
