Minor cleanup/formatting
General refactoring and renaming for better consistency
Work on making the search stuff cleaner and more flexible. Added some
charts on the index page which use various different faceted search data
via actions in a new admin Metrics controller. All this stuff is liable to
change greatly in the coming weeks.
Minor tweaks to the default routes
Prevent form submit (fixing stupid FF-only bug.)
Add an ajax spinner, and use it while loading graphs
Remove spinner on plot render
Fix css
Ensure a placeholder user is instead of nothing when indexing accessors
