Rename ecosystem_grid to have more conventional file extension
Add LifeApp to contain EcosystemGrid for a given game

Instead of rendering a 'show' page for each game and rendering the
EcosystemGrid on the 'show' page, this will be a truly one page app.

The LifeApp will have access to all games via the GamesStores, and will
render a GamesIndex sidebar that can change the 'currentGame' in the
GamesStores.
Add games index JBuilder partial

Having a top level 'index' JBuilder template **and** a partial that
renders the same thing makes it easy to use the same JSON template for
both the API response and the bootstrapped JSON.
Render LifeApp on games index view

We are about to move to a single page app format, with the main app page
being the games index.
Fix syntax to use instance of Dispatcher

The Flux.Dispatcher is a constructor, and we need to use an instance of
it to actually call methods. Using 'extend' or 'merge' didn't seem to
work to create a constructor that inherits from Flux.Dispatch, so I
hacked a set of helper methods that close over the instance of
Dispatcher, exposing a modified and limited set of methods.
Remove extra Rails views for games

Since we are moving to a one page app, these autogenerated views (which
I used to test the MVP of a game of life CRUD app) are no longer needed.

We can also lose the corresponding routes and controller methods.)
Fix minor bugs with fetching of Game data

It was time to clean up the code and fix some bugs in the Stores,
LifeApp, and WebAPIUtils related to the fetching of all games from the
server.
Fix url, path to partial, and partial JBuilder code

Several things were wrong, and were preventing the games JSON from being
returned by the Rails application.
Add code to send, process, and receive game index JSON

The last pieces of the initial games render are falling into place:
 * The server actually needed to send the list of games
 * The callback registered in the GameStores needed to update it's local
version of the games data
 * The JSON returned by the server was converted to an object to make
accessing and updating individual games more efficient.
Add 'current_game' to GameStores

The current_game defaults to 1 - it is the 'id' of the currently viewed
game, and 1 is the index of the demo game seeded in the db.
