Allow timestamps in YouTube URLs

YouTube videos are often long, containing many ascents. User who opens a beta video doesn’t want to browse through a long video to find the correct climb.

Some users who post beta videos, write the timestamp of the correct ascent in the description. Even better would be to allow timestamp in the YouTube URL (

https://youtu.be/XXXXXXXXXXX?t=123s). The video would automatically start from the correct spot. For some reason 27 Crags filters out the query string from the URL.
