Waffle Due Dates

Improves Waffle.io with recognition for due dates Chrome extension that adds "due date" recognition to waffle.io. Simply add text to cards/issues like "Due 9/1 - Do a thing" or "Issue name blah blah (due 10/12/2016)" Cards with due dates in them have: - Get a special label indicating how far until they're due - If the card is due "soon" (defined as within 3 days) it gets highlighted with a clock icon. - Overdue cards get a warning icon - Column headers get a clock icon if there are any cards due soon within the column.
