Usage stats graph initial load display

[crowesn]

Fixes #851

Turbolinks is preventing the stats graph from displaying on initial load. Disable turbolinks to prevent the graphs pulling from cache on load.

Changes proposed in this pull request:

• Add overrides for work and file_set show_actions views
• Add data param to Analytics link helpers to disable turbo-links
• Add feature spec to check for turbolinks param
