    Match Dev/Prod parity for Index Page

    schneems committed
    With Rails 4 the default index page was moved from a static file `index.html` inside the `public/` folder to an internal controller/view inside of the railties gem. This was to allow use of erb in the default index page and to remove the requirement that new apps must delete a static file to make their index pages work. While this was a good change, the functionality was unexpected to developers who wish to get their apps running in production ASAP. They will create a new app `rails new my app`, start a server to verify it works, then immediately deploy the app to verify that it can start working in production. Unfortunately locally they see a page when they visit `localhost:3000` when they visit their production app they get an error page.
    
    We initially anticipated this problem in the original pull request, but did not properly anticipate the severity or quantity of people who would like this functionality. Having a default index page serves as an excellent litmus test for a passed deploy on default apps, and it is very unexpected to have a page work locally, but not on production. 
    
    This change makes the default index page available in production if the developer has not over-written it by defining their own `root` path inside of routes.

    Use Rails to Render Default Index Page

    schneems committed
    This is an alternative implementation to #7771 thanks to the advice of @spastorino
    
    Rails is a dynamic framework that serves a static index.html by default. One of my first questions ever on IRC was solved by simply deleting my public/index.html file. This file is a source of confusion when starting as it over-rides any set "root" in the routes yet it itself is not listed in the routes. By making the page dynamic by default we can eliminate this confusion.
    
    This PR moves the static index page to an internal controller/route/view similar to `rails/info`. When someone starts a rails server, if no root is defined, this route will take over and the "dynamic" index page from rails/welcome_controller will be rendered. These routes are only added in development. If a developer defines a root in their routes, it automatically takes precedence over this route and will be rendered, with no deleting of files required. 
    
    In addition to removing this source of confusion for new devs, we can now use Rails view helpers to build and render this page. While not the primary intent, the added value of "dogfooding" should not be under-estimated.
    
    The prior PR #7771 had push-back since it introduced developer facing files. This PR solves all of the same problems, but does not have any new developer facing files (it actually removes one).

    /rails/info/routes path shows routing information

    schneems committed
    Will show similar contents to the output of `$ rake routes` in the browser in development. This speeds the time required to generate routes, since the application is already initialized.
Something went wrong with that request. Please try again.
