Automated xacts may now contain "deferred tags"

For example, consider the following automated transaction:

  = /Food/
    ; Next Date:: date + 10
    (Expenses:Tax)                1.00
    ; Next Date:: date + 20

This will add a metadata field named 'Next Date' to the _matching
posting_, with a value that is 10 days later than that posting.  It will
also generate a new posting for that transaction, whose amount is the
same as the matching posting.  Further, it will add a 'Next Date'
metadata tag to the _generated posting_ whose value is 20 days later
than the date of the matching posting.
