Bug 31409: Set focus for cursor to Fund code when adding a new fund

This makes sure that the focus is on the first input field
of the form when adding or editing a fund.

To test:
* Go to administration > funds
* Add a new fund to the budget
* Verify the focus is not inside the form
* Apply patch
* Verify the focus is now in the first form field "Fund code"
