#546 - Upgrade oauth2_provider engine to 1.0.3b.

From: https://github.com/sachinsudheendra/gocd_oauth2_provider_engine/releases/tag/release_1_0_3b
#546 - Remove assets JS files from engine.

Intereferes with Go build.
#000 - Ignore cipher in rails.new.

It looks like it is created when the server is started
to run sass and compress JS.
#546 - Change path of OAuth gadget provider engine.

It's now /oauth instead of /admin/oauth and the admin routes
inside it are /oauth/admin/...
#000 - Explicity disallow user access to /api/support.

It was not going to work for a user, anyway. But, this disables access
at a much earlier level.
#546 - Fix oauth tokens user page.

Brings over my-cruise layout from old Rails.
#546 - Remove duplicate localize message.
