Change ./ext/string requires to react/ext/string

[makevoid]

I've found that there is a require error trying to bundle the code if the the ext/string path is not absolute (gem dir / path)

I think it works well when you are requiring the gem via path: "./.." like you do in the examples (in fact they work) but it breaks otherwise

fiy I'm on 2.1.6

Here's how to reproduce:

Gemfile

source "http://rubygems.org"

gem "react.rb", github: "zetachang/react.rb"

build.rb

require 'bundler'
Bundler.require

Opal::Builder.build('react')

run:

bundle && ruby build.rb

this pr should fix it

there is also some whitespace removal, If you want I can take it out from this PR and have just the two require lines as modified

also, very cool library! I will start to play with it soon! thanks!

@makevoid can you paste the error you're getting after bundle && ruby build.rb?

[makevoid]

sure!

makevoid@mknix:~/apps/react-rb-builder$ ruby build.rb

here's the full repo https://github.com/makevoid/react-rb-builder you can switch from the fixed to the original version by changing the file

I had errors due to the same require. Manually requiring 'react/ext/string' fixed them for now, but imho this pr should be merged.
