testing the book zeroing code (maybe for backport?)

[Derek Atkins]

Hi,

Over this weekend I implemented a simple book closing feature
that lets you zeroize the Income and Expense accounts into
Equity.  It's comprised of changesets r16713, 16714, and 16715.
It's only impemented in the trunk branch at the moment.

Please test and comment and let me know if you find any problems with
it.  If it works well and doesn't have many issues maybe we can get it
into 2.2.3 or 2.2.4.

Thanks,

-derek
