Auto merge of #322 - Lakelezz:warn_log_removal, r=jdm

Removed warn-log `stop_parsing not implemented, full speed ahead!`

As mentioned in #219, `stop_parsing` was assumed to be useless. It still triggers in my project, hence considered removing it.

Hopefully this PR is okay, despite already being assigned to @nox. I simply encountered it a few days ago and decided to make the move, as this issue seems to be there for a while, I preferred to do it myself than bothering anyone for such a small fix : )

Not sure if `"FIXME: </script> not fully implemented"` can be removed as well, if so, just inform me and I will change that as well!
