* Reworked scanner registration. Scanners are getting cleanly unregistered

on wlan stack shutdown, now.
* Added patch by mmlr to support IBSS (aka Ad-hoc) mode. To activate IBSS mode
  one would need recompile the wlan stack, though, once the constant in
  start_wlan() is switched from IEEE80211_M_STA to IEEE80211_M_IBSS. There is
  no runtime configuration, yet.
