Server-side rendering caches components.js in development mode

[eins78]

While investigating #57 I came across a bug which might be the cause for many of the problems people are experiencing while trying out server-side rendering:

The components.js file is cached, even in development mode!
That means changes are not picked up until the rails server is restartet, hich causes confusing errors like [React::Renderer] ReferenceError: MyComponent is not defined even when it clearly is included.

To reproduce:

1. app/assets/javascripts/components.js:

   /** @jsx React.DOM */
   
   var DummyComponent = React.createClass({displayName: 'DummyComponent',
     render: function () {
       return (
         React.DOM.div(null, 
           this.props.text
         )
       );
     }
   });

2. Put this in any view:

   =react_component('DummyComponent', {:text => 'Hello'}, {:prerender => true})

3. bundle exec rails s

4. load the page corresponding to the view from 2..

5. add the following anywhere in app/assets/javascripts/components.js;

   throw "WTF"

6. reload page – it does not throw

7. restart server and reload page – does throw

I just reproduced this in the dummy rails app included with the tests, so it should not be caused by something specific to the app I am working on.

This has been driving me nuts, too. I added pull request #59, which fixes this bug

This should probably be closed now?
