Allowing to use arrow keys while windows (e.g., ware statistics) are open.
Changed two points:
- The UI::Panel no longer grabs the keyboard focus when it is clicked but
shouldn't grab it
- Some components (buttons, slider, checkbox) no longer accept the keyboard
focus. I don't know why they ever did so, though. It possibly was connected to
the Panel being able to switch between components with the Tab key. But since
nearly no component handles any keys, I guess it is no (big) loss. But still my
main problem with this merge request is: Does someone knows about or finds a
functionality that breaks due to the no longer applied keyboard focus?
