Title of Bug: Broken Youtube embed

Description: 
Forums acknowledge only the first argument from the Youtube embed link and ignore others

example:

*?autoplay=1&start=10
will only enable autoplay and ignore timestamp

*?start=10&autoplay=1
will only timestamp and ignore autoplay

This can be done with N arguments and only first one will be acknowledged and used.
