There are no sub-windows in g2.  There are only windows that can contain
a variety of page types (account hierarchies, registers, reports, etc),
and single purpose dialogs.

Splits and Accounts aren't the only things that get dirty.  Stock quotes
and commidities are two others.  I want a simple test on the *book* that
I can use to see if anyting in the book (split, stock price, etc) is
dirty.  Preferably a trivial test, as it will be called frequently.

Neil mentioned he will be modifying the code to use the new function
qof_instance_set_dirty() to set dirty flags on collections.  If this
function also sets the dirty flag on the book containing the collection
then I have almost every thing I need.  In a perfect world, after
setting the book dirty flag the code would also call a hook list of
functions.
