* split travelmate.s in a new central travelmate function library (usr/lib/travelmate-functions.sh) plus a smal service script (/usr/bin/travelmate-service.sh) * the vpn-, mail- and login scripts are now using the central function library * rework the ntp hotplug script * harden the config parsing * support the curl interface option to specify which network pathway is used for outgoing requests * the travelmate status now includes the backend- and frontend version information * LuCI: use a special travelmate interface, e.g. trm_wwan or use an existing wwan interface * LuCI: no longer call the logread binary, use rpc / the ubus log object instead * LuCI: various code cleanups * LuCI: various small usability improvements * readme update Signed-off-by: Dirk Brenken <dev@brenken.org>
