Case sensitive routes

[paustria]

For this enhancement: #5435

In #5435, I implied that there were five lines to change for this to work, but upon further review that number is actually eight. This has three of them, but is missing the changes to Route.js and Switch.js to support the sensitive prop. 😄

@pshrmn Updated, sir. Thank you for giving the 8 lines hint. :)

@timdorr It looks like this got missed in the react-router-dom UMD build (ctrl+f "sensitive"). I just did a local build and it worked, so I'm not sure of the exact cause, but maybe the symlinked node_modules/react-router was stale?

Well, crap, everything is on my laptop at home. I'll take a look at it tonight.
