Some minor spacing detail updates

### Overview ###
I've added some padding to the job divs so that the text is a little more separated from the div wall. I've also allowed the failed jobs to fill the blank space a little more, so they don't look so weird when you have a mix of both failed and passing jobs on the screen.

### Tested on ###
Firefox 15
Chrome 21
IE 9
IE 8 & 7 (in compatability mode)
