qRFCview Proxy Patch

This patch enables qRFCview to load proxy settings from environment variables such as "http_proxy" and "socks_proxy". Yes, popping up a dialog to set these things is fancier, but that means more coding work. I am pretty satisfied with this solution.

You can download the modified source code tarball from http://share.solrex.org/ibuild/qrfcview-0.62-solrex2.tar.gz . Binary packets for special Linux distributions can be found at http://share.solrex.org/ibuild/ too.
