date check request

[Blair Lowe]

Hi,

It would be nice if gnucash had a preference that checks to see that the
bill, invoice, or payment dates that you are entering fall within a
specific period.

It is so common for a user to enter the wrong year, and a warning
message (if the preference is activated) would be great to reduce out of
range errors.

This becomes crucial when more than one year is in the books.

Blair.
