Fix response entry admin form

It was kicking up an ALLOWED_HOSTS error since the post we were doing
didn't have an HTTP_HOST set.
[bug 1066618] Tweak Gengo account balance warning
Update ElasticUtils to 0.10.2

This is mostly cosmetic since we don't use bulk for anything other
than insert.
Codify nose arguments

This simplifies the documentation around testing by codifying arguments
we should be using by default in local.py. Less noise ftw!
[bug 1020303] Add rating column

This adds a rating column which is like the happy column, but allows for
a gradation of values.

If we get a response with a rating, but no happy, then we'll populate
the happy accordingly--we always want to have a happy.

However, if we get a happy, but no rating, we won't populate the rating
column--we'll leave it null.

This allows us to A/B test the two and distinguish between which version
of the form the user saw and correlate that to the answer they gave.

[bug 854479] Fix ui-lightness 404 problems

This was a tricky problem with paths between our server environments and
development environments. I moved some files around so the relative urls
that jquery-ui.css use are correct for both the minified dashboard.css
file which we use for server environments and the jquery-ui.css file we
use for development environments.
