travelmate: update 0.6.0

* rework automatic mode (active scan/re-connection handling):
   * much more procd & resource friendly
   * now enabled by default
* save runtime information in ubus service (data section)
* final backend preparation for new LuCI-GUI (still WIP!)
* documentation update

+    * trm\_automatic => keep travelmate in an active state (default: '1', enabled)
+    * trm\_maxwait => how long (in seconds) should travelmate wait for a successful wlan interface reload action (default: '30')
     * 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\_timeout => timeout in seconds for "automatic 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)

+**receive travelmate information via ubus:**
+<pre><code>
+ubus call service get_data '{"name":"travelmate"}'
+This will output the current connection status, e.g.:
+{
+    "travelmate": {
+        "travelmate": {
+            "last_rundate": "02.04.2017 07:22:03",
+            "online_status": "true",

+            "station_radio": "radio1",
+            "station_ssid": "blackhole",
+            "system": "LEDE Reboot SNAPSHOT r3888-8fb39f1682",
