Fix extract_polymer_config

Browse source 
The `ytInitialPlayerResponse` regex can now handle `var` and `window`
assignments.

The video streams can now be extracted from `player_response` and
`initial_data`.

This fixes the descriptions on videos and videos themselves. Videos are
technically broken right now, but work becasue of a fallback that goes through
embeds.
