Closes #849

[houndci-bot]

Identifier 'spotlight_users' is not in camel case.

There is a bit of a spacing issue in the form where the label has .sr-only as well as a .col-md-2 but the .col-* declaration is keeping the allotted space available. I don't see why the .col-* class isn't being added other places where we're using hide_label: true.

If anybody has any ideas as to why this is happening or proposed solutions, I'm all ears.

[jkeck]

Odd about the reduced coverage. I think it's caused by relevant lines of code being moved, but that code is tested elsewhere (and showing 100% coverage). It seems strange to me that this would cause a drop of 0.2%.

[cbeer]

Agreed about the coverage; the coveralls report is less than helpful.

Should we wait to merge this until we can look at the label spacing problem?

[jkeck]

Yeah, maybe I can show you what is going on. It's pretty minor so we can fix it up and later today or tomorrow.

I've fixed the label padding problem -- it looks like the horizontal form layout (which we didn't actually seem to need) forced columns on us.

Ah! Makes perfect sense. Thanks @cbeer!

I'm not sure about perfect sense, but it probably helps keeping things aligned (and if we weren't using tables, we might need it..)
