Latest EXTINF format

This library is unable to parse m3u file given in link.

@abkNiazi The latest specification does not provide support for "attributes" in the #EXTINF tag:

http://tools.ietf.org/html/draft-pantos-http-live-streaming-19#section-4.3.2.1

I've seen specially formatted titles contain key value pairs, but that has to come after the comma that separates the duration and title. We do support a parsing mode to parse a negative duration.

So basically, SS IPTV is producing playlists violating the specification. There's two ways to handle this:

1. ask SS IPTV to change how they produce playlists
2. create a special parsing mode to handle this case somehow

Option 1 would be best IMO. If that's not possible, I propose the following solution to option 2:

• add a MediaPlaylist.getRawExtinfTags() method
• add a parsing mode flag to allow improperly formatted #EXTINF tags
• if the parser encounters a bad #EXTINF tag while using that parsing mode, it will be added to the MediaPlaylist.getRawExtinfTags() list and continue parsing
• it is the up to the client code to pair up the raw #EXTINF tags with the tracks and do its own parsing of SS IPTV's "attributes"

This is not ideal, but this library cannot build a consistent API if we assume too many special formats from 3rd parties.
