whomp-whomp view uses all the cpu

[dshusta]

There's a weird invisible div pattern thing called #whomp-whomp which constantly neverendingly animates, using 100% cpu despite doing nothing.

Steps:

1. go to http://ci.pivotallabs.com
2. make sure there's a project tile with Tracker story breakdowns visible
3. look at activity monitor

Expected:
Nothing is changing on the screen, so ~0% cpu usage

Actual:
Nothing is changing on the screen, but ~100% cpu usage.

The culprit is a sub-element of the #whomp-whomp pattern:

Crazy! I believe this is the element that animates the accepted column when the current week's velocity is higher than rhe average. This behavior is not the intent, though.
