CC2646: Set a calendar view default (Day/week/month) that's remembered

Updated the calendar page so that when user chooses a different time scale to display(day/week/month),
the new setting is stored in the pref database. Each user id has its own entry in the database.

When visiting the calendar, we retrieves the entry from database for current user
and show that time scale; defaults to monthly view if no entry found.
