[evolution] EMFormatHTML: Configure CamelHttpStreams with proxy authpass.

[Matthew Barnes <mbarnes src gnome org>]

commit 9773f0a3b8ed4a058d4cd28d0bc4060dbe43da19
Author: Matthew Barnes <mbarnes redhat com>
Date:   Sun Sep 25 20:42:38 2011 -0400

    EMFormatHTML: Configure CamelHttpStreams with proxy authpass.
    
    Base64-encode the "USER:PASS" authentication string ourselves and hand
    it to camel_http_stream_set_proxy_authpass().
    
    This is so I can kill camel_http_stream_set_proxy().
