Qtella

When moving through the search tabs, the various search
options (audio, image, minimum line speed, etc...)
aren't updated, while they're saved in the data
structures. Stated another way, the status displayed by
the interface isn't consistent with the internal state.
It even gets worse when using the "resubmit" button,
where the sent query is the one displayed by the
interface, not the initial one.

The patch changes this behaviour by positioning the
interface checkboxes and comboboxes according to the
internal state when browsing through the search tabs.
