Added controls, show month name on xs devices

Added .col-xs-6 on left and right control buttons so that extra small-device users can switch months on calendar. The title button goes away to prevent buttons from being smashed. Month names were now programmed correctly so that on extra-small devices, even without the weekdays showing up in their own row, users know what weekday and month it is on each respective date in the calendar.

Added word-break/word-wrap for calendar labels

To prevent excessively-long words from breaking the calendar, word-break and word-wrap properties were defined in CSS so that words can be broken up by letter to prevent the structure from going haywire.
