Added simple (non-auth) proxy support including processing the second set of headers (server) vs first (proxy). New command line option (-j 127.0.0.1:8888) to set the proxy and port. unfortunatly both -p and -x were already taken

extended refresh header handling to libcurl and safecurl
also some minor tweaks needed to have Curl 'behave' with certain servers by adding accept-language header to Curl
Added ability/template to allow the user to select their own SiteURL (see BitSoup implementation) with a minor update to ConfigurationData class to prevent the "display text" from disappearing on errors.
XSpeeds indexer - updated to handle a case where the returned XML occasionally is null terminated resulting in XML parsing exceptions
BitSoup indexer - added user customizable url selection, including some url validation
BaseIndexer - cleaned up some of my earlier implementation for accumulating cookies.
