This functions well, there are just a few minor nits to pick as far as cleaning up the code and making sure the tests are actually testing.

Looks good to me.

Just remove the large commented block from packages/app/obojobo-repository/shared/components/people-search-dialog.jsx and it should be all set.

I merged in dev 30 except four style files which have lint errors. These lint errors appear to be already in dev30, so if I alter the files in order to commit them then they will continue to show up on this PR diff. I was not sure if that was ideal so I didn't not commit those files yet. They show up in the diff right now without the dev30 merge updates.

merged with Dev 30 and lint style updates made in 4 files. These four files more-info-box.scss, objective-list-view.scss, search.scss, and objective-item.scss are seperate from this PR, but needed their styles to be updated to be merged in. I also removed the commented code requested to be removed above.

Code isn't building to test, see below.

Looks like this is working properly and performing as advertised.
