usability tweaks and starts basic support for printable calendars

- Adds description text above search box
- Changes Search to Find Address
- Adds print button
- Hides unnecessary divs in print view
- Adds Calendar HTML/Calendar.css to create a printable calendar 
I know this is a result of feedback from user testing, but "Find Address" seems a bit odd on this button. Technically we're finding a schedule for the entered address, so it seems misleading.
