* cybwifi: send USR1 signal to 'autossh' when the network has been restarted if
  any 'autossh' process has been found
* cybwifi: sleep longer when checking eth0 link because 2s doesn't seem enough
  with Intel 82579LM and Linux 3.2.0-2-amd64
* cybwifi: deal with stupid ESSID names containing spaces, asterisks, etc.
* cybwifi: turn 'eth0' down again if no network has been detected
