DiffEditor: Fix editor actions

The text editor widgets all need a TextEditorActionHandler that takes
care of the editor actions for them.
Each text editor needs its own context, so the editor with focus
receives the actions. This does not happen automatically for these text
editors, since the diff editor manages these itself.
