Issues with Draytek routers

[oviano]

Hey there

1. WANIPConnection is not found in the response from three different Draytek routers (2866, 2862, 2927):

2. Ok, so if I hack the code everywhere it says WANIPConnection to use WANPPPConnection then it starts to work. But then fails trying to extract ExternalIPAddress from the following response:

<s:Envelope xmlns:s="http://schemas.xmlsoap.org/soap/envelope/" s:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/"><s:Body><m:GetExternalIPAddressResponse xmlns:m="urn:schemas-upnp-org:service:WANPPPConnection:1">XX.XX.XXX.XXX</m:GetExternalIPAddressResponse></s:Body></s:Envelope>

This is caused by the presence of the datatype information immediately after NewExternalIPAddress. If I add further hacks to the code to take into account this string then it works and maps the port correctly.

It looks like the routers implement the WANPPPConnection service instead of WANIPConnection. The UPnP standard is such a mess...

I think the library be adapted to support both. If you already have working code, a PR would be welcome.

Great, I'll sort out a PR for this.
