Reduce warning spam

[jdm]

Two of the most common warnings I see reported in Servo's automatic reporting system are stop_parsing not implemented, full speed ahead! and FIXME: /script> not fully implemented. We should investigate what those mean and remove them if they're not actually useful.

warn!("FIXME: </script> not fully implemented");

warn!("stop_parsing not implemented, full speed ahead!");

The </script> warning was tied to issues #7 #19.

As for stop_parsing, I assume that since it's this rule and from what I can tell, it depends on hooking into Servo so JS can write stuff.

</script> has been taken care of. Will look into stop_parsing.

I'm pretty sure stop_parsing is useless now, will clean up.

Is this already released...? Seems 8 yrs ago, and not sure details, but it's still open...? I'm using 0.27.0, and it seems it's still happening.
