SSLv3 discontinued (CVE-2014-3566)

Due to the SSLv3 CVE-2014-3566 vulnerability, the Dailymotion API servers are about to drop SSLv3 support. This change allows PHP to chose the best SSL version available by itself. Please update your installations!

Better documentation + fixes

• Better documentation to address misunderstandings about how the SDK works regarding authentication.
• Exposed the Dailymotion::getAccessToken() method for those who hate lazy authentication.
• Fixed issues with the current URL detector.

Minor warning fixes + progress_url

• Fixed the strict standards warning thrown when calling Dailymotion::httpRequest().
• Fixed a scope issue when calling Dailymotion::getAuthorizationUrl().
• Added a way to retrieve the progress_url from Dailymotion::uploadFile().
• Fixed an issue with cookie session storage trans-typing when getting an access token.
