- the server log view is not cleared when saving the log (but old messages are removed when going over the max number of lines)

- log can be viewed in the server lobby, not just in-game
- logging pump, reactor & battery state usage
- GUIListBox.MouseRect doesn't return an empty rect anymore -> listboxes without selectable content can be scrolled with the mouse wheel
