Add TestPage component and dummy content to other components

I updated the react component generator to add dummy content to each
component's 'render' method, because webpack was throwing a syntax error
on the final semicolon after the 'return ();'.

The TestPage component will be a place to render other components while
I'm working on them.
Generate dummy content in react component skeletons
Fix typo in README
Update Accio to 2.1

Accio can now run a generator multiple times. This is specifically so I
can do this:
> accio react_component nav_bar test_page button field_input

That will generate 4 component skeletons in one command, instead of me
having to type the 'accio' command 4 times.
Fix issues with react_component generator

 - Add quotes around require argument
 - Add missing space in dummy content
 - Take a string as an argument instead of an array
Regenerate component skeletons with updated Accio and generator

These component skeletons were generated with one command line call.
Hopefully they will compile smoothly now that the typos and issues in
the react_component generator have been fixed.
Render the TestPage in the index view
