Web Proxy Capability

[wiebersk]

I was having problems using Ruby 1.9.3 connecting to SalesForce using this gem. It looks like Net::HTTP.new takes different sets of arguments if a proxy is needed so I modified the https method in the SalesforceBulkApi::Connection class to the following:

def https(host)
      req = Net::HTTP.new(host, 443, @proxy_url, @proxy_port, @proxy_user, @proxy_pass)
      req.use_ssl = true
      req.verify_mode = OpenSSL::SSL::VERIFY_NONE
      req
 end

This seemed to fix the problem for me but I wasn't sure how you wanted this worked into the Connection class. I was thinking of setting proxy variables in the connection from the Restforce/Database.com client if the proxy_uri option is set. If you think this is a decent approach, I'll work it up and send in a PR for it.
