wish: 1- and 2- week options for budgets

[David McAuliffe]

Budgets: expand the budgeting interval to include 1- and 2- week options.

My income (and expenses) are paid 2-weekly. This means that my income and expenditure does not neatly fit into the "monthly" budgeting framework- there are two months a year where I I have three pay-intervals in a month. A monthly budget it clumsy.

Could be achieved in Manage Budgets dialog, massaging the "is the same" and "is different" options. A perfect dialog for me would include the option to select a every month, or different value every (select interval).
