saving budgets

[Chris Shoemaker]

The current budget design seems to assume that created budgets will
live with the accounts.  (There's no mechanism for saving or
retrieving budgets from files.)  This makes sense since a budget seems
pretty strictly dependent on the account heirarchy.

So, if no one else is working on it, I'm considering trying to store
the budget in the same place that the accounts are stored.  (I haven't
looked into the details, yet.)  Any comments?
