Youtube playlists and timestamps #170

The YouTube URL mangler (#26) removes playlist info (?list=) and timestamp (?t= or ?start=).

A URL like https://www.youtube.com/watch?v=...&list=...&t=... should be converted to https://www.youtube.com/embed/...?list=...&start=....

embed URLs support start but not t. The value has to be a number in seconds.
watch URLs support both start and t. The value is usually a number in seconds, but it can also have explicit units like 70s or 1m10s.

Fun fact: Discord has a similar bug / lack of a feature. When you post a message with a YouTube link, Discord attaches an iframed preview. It handles unitless timestamps, but not units or playlists. If you post https://www.youtube.com/watch?v=...&list=...&t=1m10s, the iframe has source https://www.youtube.com/embed/...?start=1m10s and the video starts at 0:00 because 1m10s is not a valid number. The playlist is simply ignored.

I also tested Slack, Facebook Messenger, and GitHub, but they don't have video previews like that.
