CURL SSL Version option.

I had a problem connecting to a feed and I found that the problem was with tomcat and a good way to fix it was changing the ssl_version.

I added the parameter the ssl_version parameter option to be set in curl.

Also I added the verify_peer parameter. I know it is not recommeded for production enviroments but it is very usefull in development environments.

Thanks a lot fot this gem. :) Great job! :)
