Upgrade jquery-ui-rails from 4.1.1 to 5.0.0

This adds the capability to be compatible for the jquery-ui-rails 5.0.0 gem. Resolves issue #640. This pull request doesn't involve changing any any testable dependencies so no test are being submitted. Changing only the gemspec dependency from 4.1.1 to 5.0.0 did cause many tests to fail. Fixing the naming scheme throughout the app returned the app to a passing state. I did build a fresh alchemy app using these changes and tested out the UI and everything worked well from what I could tell.
