Title: Datepicker: Better guess for a missing year in parseDate

Currently when "guessing" the year in parseDate('d/m') the current year is simply used.
A better guess would be to pick the closer date to today. If the date is Jan 2012, and someone enters "Dec 25" they propably mean last year not this year.
So if the given month is more than 6 months earlier/later than this month then guess next/last year.
