Explore whether we need to include all of react-bootstrap in vendor.js

Pointed out by @taion on an unrelated PR (and project):

On a complete tangent, because I don't know the meaning of the word off-topic, I noticed that you guys were pulling in all of React-Bootstrap (and other libraries) for your vendor bundle. Is there a benefit to doing things that way? Seems like you end up with a lot of stuff in your vendor bundle that you couldn't possibly be using.

Basically, we only use Modal and Tooltip from react-bootstrap, but it seems we're pulling in all js for every conceivable component. We should investigate further.

Interesting - if that's your use case, you might be interested in https://github.com/react-bootstrap/react-overlays, then, which just pulls out the core stuff behind the R-B Tooltip and Modal components and doesn't have all the Bootstrap stuff.

Closing this issue due to staleness. Feel free to comment here if you think we should still work on this.
