- Removed annoying bug: "Error: can't read "": no such variable".
(On GUI startup "Select tool" is not selected. If you try to select
something using left mouse button an error is displayed.)
- Use default font for all menu fields.
(Removed "-font arial" from "Static routes" field)
- Mode for "host" is always "static" (not quagga or xorp)
(If all nodes are selected for "Routing protocol defaults" than
only nodes of type "router" should be efected by the change.)
