[evolution-patches] User agent patch

[Moritz Mertinkat <maurice-evolution mertinkat net>]

Hi everybody,

I've made a small patch (against SVN trunk rev 35949) to add a 
meaningful user agent to HTTP requests used for loading remote images 
from HTML mails. That way it would be possible to get better mail client 
usage statistics for future Evolution versions.

Currently Evolution only sends "User-Agent: CamelHttpStream/1.0" which 
is the default from the Camel.Stream class.

With the patch it is: "User-Agent: CamelHttpStream/1.0 Evolution/xxxx" 
(where xxxx is the Evolution version). I've kept "CamelHttpStream/1.0" 
string for backward compatibility.

The patch is attached (evolution-useragent.patch).

Regards,
Moritz Mertinkat
