Undo/Redo causes unwanted rotation

[simonbethke]

Steps to reproduce:

1. Open a scene
2. Rotated it by typing a number in the rotation
3. Make a rectangular selection
4. Delete it using the del-key
5. Undo that using CTRL-Z
6. Press CTRL-Z again (no effect)
7. Now click the Undo-Button (the selection will rotate shortly and then rotated back)
8. Click the Redo-Button (you have a rotated selection)

I suspect this has to do with the keyboard focus.

If the number entry has focus then undo is handled by the edit box itself, not the undo system.

If that is the case, you need to remove the focus when adding operations to the history stack. Also you need to ensure, that the default text-undo is prevented
