  Fireinfo could not send its profile to https://fireinfo.ipfire.org/
if the machine is behind an upstream proxy which requires username
and password. This is fixed by tweaking urllib2's opening handler.

To apply this on existing installations, the fireinfo package
needs to be shipped during an update.

The second version of this patch fixes bogus indention, assembles
proxy authentication string more readable and preserves HTTP
proxy handler.

Fixes #11905

Hello,

thanks for adding authentication and support for HTTPS to fireinfo.

You are overwriting the proxy_handler variable here and that creates 
this
only for HTTPS which is not what we want here.
