Add expression functions for handling date/time:

- year,month,day,hour,minute,second extraction - new QgsInterval objects - handles time amounts - age() function returns the difference between two datetimes - $now returns the current date and time - support for datetime - interval = new datetime - tointerval, todate, totime functions - tests ;)
