#13 Improve test job workflow

[Tim Yates]

After test jobs complete, users will almost always want to either modify and retest, or submit the job as a real Hadoop job. Currently, the best way to do it is to click the "Resubmit Job" link at the top, which is both poorly worded and not very well visible. We should either:

a) Improve the link and make it more obvious, or
b) Automatically redirect back to the job form, showing the results above or beside the form.

(b) is harder to achieve, but it is a little better from a usability standpoint, since it has errors alongside a place to fix them.
