README.textile: fix invalid option name in the example (`-port` instead of `-proxyport`)
Updating sample code to explicitly use tls1.

Since the announcement of the Poodle attack, many sites have disabled
use of ssl3, including check.torproject.org. This patch updates the
sample code in the README to explicitly use tls1 for connections.

This closes issue #2.
Merge branch 'master' into socket-async
