When clicking the "OK" button, the "hook" function tries to save the specified
ssids of hidden networks. Earlier, this call was being executed, irrespective of
the presence of "hidden-network-connect" rpm. However, that would result in an
exception.

Fixed this - now the call is made, only when the "hidden-network-connect" package
is available.
