travelmate: update 1.2.1

* no longer rename faulty uplinks in /etc/config/wireless, but save
uplink state in json runtime information. To reset the saved state
simply restart travelmate processing.

 ## FAQ
-**Q:** What happen with misconfigured uplinks, e.g. due to outdated wlan passwords?  
-**A:** Travelmate tries n times (default 3) to connect, then the respective uplink SSID will be marked / renamed to '_SSID_\_err' and travelmate no longer attends this uplink. In this case use the builtin wireless station manager to update your wireless credentials.  
+**Q:** What happen with misconfigured, faulty uplinks, e.g. due to outdated wlan passwords?  
+**A:** Travelmate tries n times (default 3) to connect, then the respective uplink will be marked as "faulty" in the JSON runtime file and hereafter ignored. To reset the JSON runtime file, simply restart travelmate.  
 **Q:** How to connect to hidden uplinks?  
 **A:** See 'example\_hidden' STA configuration above, option 'SSID' and 'BSSID' must be specified for successful connections.
