travelmate: release 0.4.0

Browse Source 
* add an "active mode", where travelmate will be restarted
  every n seconds (default 60) and checks existing uplink connection
  regardless of ifdown event trigger (disabled by default)
* enhance multiple radio support
    * fix the ap detection
    * respect different radios during scanning & connection handling
* cosmetics

* trm\_active => keep travelmate in an active state (default: '0', disabled)
* trm\_maxwait => how long (in seconds) should travelmate wait for wlan interface reload action (default: '20')
* trm\_maxretry => how many times should travelmate try to find an uplink after a trigger event (default: '3')
* trm\_timeout => timeout in seconds for "active mode" (default: '60')
* trm\_iw => set this option to '0' to use iwinfo for wlan scanning (default: '1', use iw)
* trm\_radio => limit travelmate to a dedicated radio, e.g. 'radio0' (default: not set, use all radios)
* trm\_iface => restrict the procd interface trigger to a (list of) certain wan interface(s) or disable it at all (default: not set, disabled)
