Fix Android TV support (closes #21)

[sleeyax]

Turns out it was a multitude of issues:

• Spaces in the id field (on other platforms its not an issue because it gets urlencoded i presume).
• Use of the deprecated title field in the stream object (description was also set, which is its successor).
• Missing fileExtension and videoSize fields in the behaviorHints field (probably not the issue though).
• Unnecessary 'authentication' suffix at the end of the stream url.
• Infinite loop in the 'search all' api method
