WIP: adding testing about integers
WIP: view-by on integers
View-by for Integers
Adding dates
Adding a generic get-icon function for fields, cleaning up field type checker names
Adding icon to map viewby
tiny refactor; using ona.utils.forms rather than type strings directly
Clicks were getting cleared on view-by-close. Fixing that
Nicer date formatting using momentjs
Better formatting + view-by-binning for dates
Moving charts tests to their correct place
Providing properly sorted bins for dates and ints
Defaulting count to 0, and not displaying q/a in submission legend if no answer
Makes string / note / group fields unclickable, adds a test that string fields have a blank href; closes #1074
Should fix tests, as well as address @pld's code review comments
RR: change 404 message in test
