Make "most local url" determination asynchronous so that it doesn't block the GUI for a long time

 (e.g. when accessing the non-existing sftp://192.168.1.100/home)
and only run this job if the terminal panel is shown (or at the time when it is made visible).
Sorry kdebase users, you get to update kdelibs again.
