Adds CSS id graphiql-rails to html tag
Includes the id in the html and body css rules.

With these changes, I'm able to require your CSS / JS base application files without effectively altering my host app's html and body rules. I'm doing that so I can embed GraphiQL in my existing stack with authentication, look-n-feel etc.

As I'm using it	When used normally (nothing changes)

To do this I copied in two files making changes to use our layout.

/controllers/graphiql/rails/editors_controller.rb
/views/graphiql/rails/editors/show.html.erb

Host application.css

 *= require graphiql/rails/application

Host application.js

//= require graphiql/rails/application

TLDR;

To avoid requiring versioned CSS files that will cause headaches with graphiql-rails updates, I added a CSS id to increase specificity.

rmosolgo / graphiql-rails

CSS change to allow easier integration into existing Rails stack #78

Host application.css

Host application.js

TLDR;
