Title: Adding proxy options to check when a Gravatar exists

I've added the option to use a proxy when a user requests if a gravatar exists. Currently it's using fsockopen. At our company this is a problem as our servers don't have a direct connection to the internet, everything goes through a proxy.

I've replaced fsockopen with curl as curl offers out-of-the-box options to specify a proxy. By default there is no proxy.

If you'd like me to add options to specify a username and password for a proxy that needs authentication, do not hesitate to let me know. Thanks.
