Kh print calendar

@boonrs @drewrwilson 


This commit adds javascript for generating printable calendars and uses the JS in calendar.html with fake data. calendar-generator.js reads data in the following format:

<code> 
{"street":"Wadsworth St", "date":"2014/01/13", "direction":"N"}, 
</code>

It also adds holidays to the calendar:

<code>var holidays = ['2014/03/12', '2014/05/22', '2014/04/01'];</code>

Remaining tasks (for a different branch probably)
- Hook this up to the "print button"
- Pass through data from server
- Add a printable table of the SS schedule for that address

**dateInArray** is essentially the same method as **dateInStreetSweeping**. Decide which way you'd rather check dates and delete one of the methods. Then use the method for both holidays and street sweeping.
