Changed 'Commit hash' to 'Git revision'

This makes larger libraries more cacheable and will allow us to use SRI with the dynamically included libraries.

Resolves #18894.

This reverts commit 13e37a3e.

Replace raphael-rails with raphael.js so it can be split from the rest of the JavaScript. The gem isn't maintained anymore anyway. Added a network folder with an application.js including raphael components, since that's the only page using it currently.

This reverts commit 3e991230.

These have been replaced by the "requiresInput" behavior.

Make the following changes to deal with new behavior in Rails 4.1.2:

* Use nested resources to avoid slashes in arguments to path helpers.
