flow 0.53 compatibility

[mwiencek]

flow 0.53 changed how React things are typed. They've provided a flow-upgrade utility to automatically convert things, so I've ran that to generate the changes in this commit.

Thanks for the PR @mwiencek!

As far as I can tell the new definitions for 0.53 aren't backwards-compatible, so I've created a commit here that puts your new defs in a new file - this way people on old Flow won't find their types breaking and people on new Flow can opt-in to the new types. I'll replace the definitions in the main file with the new ones in a future major version change.

Does that make sense @mwiencek? I don't actually use flow myself :).

[mwiencek]

Yeah, that sounds better, thanks. :)

It seems that flow only reads jsx-control-statements.flow.js by default (I couldn't find this behavior documented anywhere, so if you know of anything I'd be curious), so I needed the following in my .flowconfig to use the new defs:

[ignore]
.*/node_modules/jsx-control-statements/jsx-control-statements.flow.js

[libs]
./node_modules/jsx-control-statements/jsx-control-statements.latest.flow.js

Thanks for sharing that, have published a new version and linked to that explanation in the readme :).
