Add virtual Birthdays calendar computed from contacts

Browse Source 
The combined month view now always includes a read-only "Birthdays"
calendar (ref "@birthdays"), generated on the fly from every contact's
BDAY field across the user's address books — no calendar objects are
stored for it. Each birthday appears as an all-day event titled
"🎂 Name (Age)" (age omitted if BDAY has no year, e.g. "--MM-DD"), colored
pink, and links to the contact's edit page instead of an event editor.
Handles both "YYYY-MM-DD"/"YYYYMMDD" and year-less vCard BDAY formats,
and skips Feb 29 birthdays in non-leap years.
