Updated PPHttpConfig Default CurlOpts to include a cipher list

Updated to include a Cipher list so that SSL falls back correctly on Sandbox environments.

Read more about the CURLOPT_SSL_CIPHER_LIST curl option here: http://curl.haxx.se/libcurl/c/CURLOPT_SSL_CIPHER_LIST.html

TLSv1 is a cipher list provided by OpenSSL.

This pull request is to address the same issue as #54 but uses the OpenSSL cipher list instead of copying the Mozilla one directly.
