Update to resolve issue #1793

This update resolve the issue raised when you try to share a link from YouTube android app to pyLoad client.
Issue was that the parser doesn't detect youtu.be as a valid URL for YoutubeCom.py and always use BasePlugin.py instead of, that is why the "__pattern__" need to be modified.
The URL_REPLACEMENTS is not appropriate for this short url and was fixed also, in order to construct and typical youtube.com URL, that this script can handle.
