Remove heatmap tab blinking and dead styles

I find the tab blinking to be too subtle to be meaningful and not
a worthy enough feature to justify more jQuery UI use or storing
an additional property on the annotation (see #1207).

If we want a feature like this we'll have to come back and revisit
it with a more critical eye.
Kill the card animation

It slows things down, especially on mobile devices and on the stream
where many annotations are loaded at once, and it doesn't add much
as it is.

Close #1119
