travelmate: update 1.3.0 

* proactively scan and switch to a higher prioritized uplink,
  despite of an already existing connection,
  this is configurable via 'trm_proactive' option
  (default '1', enabled)
* fix some minor list trim issues
* optimize wlan scanning behavior
* refine debug messages
