This patch replaces the javascript that animates the fade-in of new bubbles with pure CSS code.
I set the animation length to 0.3 seconds, that's what I took from the other code (opacity steps by 0.1 every 30ms).

System messages should also be excluded from this animation.

After some testing, I think I prefer using the 0.5s value here. While the old removed code seems to do the animation in 300ms, I suspect there was some overhead that made it take a little more time.

>+@-moz-keyframes fadein{

Nit: Space before "fadein" and "{".

Nit: I prefer just "0" here.
