New customizable admin dashboard

[ahamelers]

A new administrative dashboard, featuring:

• Customizable returned fields, which carry over to CSV reports
• Extensive and accurate filter options, with pre-filtering and display of relevant options depending on user role
• A nifty search-to-select component for long filter lists (funders, affiliations, journals)
• Date range filters
• Manuscript ID/Related DOI search
• Comparatively fast loading
• A role switcher for people who have multiple roles (theoretical at this point, but fun for testing!)
• Saved searches (for customizing your default search, or creating several re-runnable reports)

This can be deployed for staff testing on sandbox, and even on production (it does not modify the existing admin dashboard at all). Once staff have had a chance to test, we can open it up to other administrative users for additional feedback.

Remaining to be done:

• Copying/moving over all the curation editing popups (when curators confirm they will use this over the existing dashboard)
• Writing/copying over extensive automated tests
• Feature to allow users to share their saved search settings (db column for a share code is there but methods and UI remain to be done)

Other tasks may be added depending on feedback.

Looks great. There is obviously a lot to test, and most of the testing is best done with real data, so we can test more with this merged....
