luci-app-travelmate: fixes for new QR code template

* remove unofficial 'WPA2' enc. token for better compatibility with
  certain QR code reader, still 'WPA', 'WEP' and 'nopass' are supported
* add WEP key slot support (not really needed, but it's still
  supported by LuCI wireless)
* correct escape single quotes and other special chars
  in SSID & passwords
* code cleanup
