Feature/updating receipts tab

[noahmanger]

With receipt aggregates now separated by those from individuals and those from committees, this updates the layout of the receipts tab to reflect the division:

This will resolve #339

The "left" part sounds more like a modifier, so should probably be --left. If there are too many places this would have to change, I don't care that much.

Hmmm. In this case I meant it as the left-side element on the section intro. I don't mind either way.

Some of these selenium failures may seem valid. Like this one:

 AssertionError: 'Oops: We messed up' != 'A WHOLE LOT OF PEOPLE FOR GRIJALVA CONGRESSIONAL COMMITTEE'
E       - Oops: We messed up
E       + A WHOLE LOT OF PEOPLE FOR GRIJALVA CONGRESSIONAL COMMITTEE

It seems like we're changing the text that appears for when something goes wrong.

Also, "WHOLE LOT OF PEOPLE FOR GRIJALVA CONGRESSIONAL COMMITTEE" is an awesome committee name.

But this ^ could also mean that search results aren't returning correctly because it can't find .tst-search_results h5 a elements or tbody tr.

I think the issue with that failure is that it's showing the error message ("Oops: we messed up") rather than the committee result. Based on all the other failures, it seems like it's just not getting any data.

I'm fine merging then, but @jmcarp this is a potential example of the tests failing randomly.
