travelmate: update 1.4.5

* add a 'Net Error Check' which treats a missing
  internet availability as an error (disabled by default)
* add a 'List Auto Expiry' which automatically resets
  the 'Faulty Stations' list after n minutes,
  default is '0' which means no expiry (old behaviour).
* rework major parts of the check subroutine
* add both features to LuCI frontend (separate PR/commit)
