Update minified version of 'create-react-class'

**what is the change?:**
We ran the latest version of
`addons/create-react-class/create-react-class.js` through https://jscompress.com/

**why make this change?:**
The last corner case I'm thinking of is this:
 - The `createClass` deprecation warning never went out in 15.5, and is going out now for real in 15.6.
 - The `createClass` UMD build is broken for AMD/CommonJS, but we fixed it. But not for the minified version of the file.
 - If someone see the warning, and tries to use the UMD build, then it's going to be broken in some cases.
 - Since we're skipping mentioning the add-ons in the blog post, and this might be a new warning for them, this could be a nasty surprise for folks.

We can do a quick 15.5.4 release of that package, we would at least fix that case.

This diverges from what @gaearon is doing to fix the add-ons. I would
probably try to use cherry-pick and interactive rebase to move this
commit to right after
facebook@ce3ecfb
and then do the patch release of `create-react-class` from that spot in
history.

Alternately I can merge this into the forked branch
`15.6-before-addon-reconstruction` and then do the patch release from
there.

**test plan:**
I didn't test this. Ideally minifying this file won't break anything,
and it's high cost to test add-ons until we have some repeatable tests
in place.
