Merged speed optimized xml backend for contacts to main.

Added QDateTime to querybyexample. For instance, it is now possible to get
all Birthdays/Anniversaries between two dates. This should be used
to show all birthdays in the datebook..
This change is sourcecode backward compatible but you have to upgrade
the binaries for today-addressbook.
