Show python code for user actions

Blender has this feature where there is a pane in which it can list python code for many actions performed by the user like for example adding an object or resizing it. This is useful to figure out how to perform a certain action inside an extension. I feel like adding a similar feature to angr management could lower the learning curve to using angr from python rather than (or in addition to) through the angr management gui.

See https://docs.blender.org/manual/en/latest/editors/info_editor.html for the blender docs of this.
