[PATCH] Fix live tv streaming broken by live rewind

[dinkypumpkin]

Instructions for updating to Git HEAD:

https://github.com/dinkypumpkin/get_iplayer/wiki/githead

The live rewind feature added to iPlayer TV broke playlist parsing for live tv
due to the addition of a 'liverewind' attribute to <item> elements.  Parsing has
been fixed.  For example of new format:
