Solve potential problems with live streams

I had some problems watching tonights live stream of the games.
Maybe it was just some server problems on the GP sid, but with this it
always worked.
Solve issue #87 - Ended games still being marked as 'Live'

Close issue #87
Simplify previous fix. Don't mark finished games as live.
Rework previous fix

Alex suggested that when the games are in this limbo phase where they
are marked as live games but have a End-Time, there are no condensed
versions available.
However the actual games have condensed versions available.
Don't rewrite game_version to keep it more clear
Use alternate manifest with support for higher bitrates

This should fix issue #93. Feel free to edit this if there's a cleaner
way to do it.
