System proxy fallback doesn't honor nonProxyHosts.

[Trinition]

HTTPClient tries to use the system proxy if one isn't explicitly set. It does this by honoring the http.proxyHost and http.proxyPort system properties to construct a proxy. It does not honor the http.nonProxyHosts system property. What this means is that while any other Java connection will honor the Proxy blacklist, wslite does not.

It might be simple to honor the http.nonProxyHosts property in the existing code. Alternatively, maybe a java.net.ProxySelector can be queried (the sun.net.spi.DefaultProxySelector already honors the blacklist).
