Change List of Dates to Date Picker

[danreale]

The list of dates is kind of sloppy. Implement a date picker where a user can click any date that has data and will bring them to the /day page.

Date picker should highlight current day with some color.(Maybe blue)
Date picker should gray out and disable and date that we do not have data for. We only started this project over the last year and there were some dates that are missing data. We don't want users clicking on those.
