Bug 14649: Fix regression - display fund name on budget planning

Bug 14649: Fix regression - display fund name on budget planning

A patch from bug 11714 removes 'budget_name_indent', which was useless.
The script and the template should use the budget_name value.

Note that this patch impacts the CSV export, which does not work, so it cannot be
tested.

Test plan:
Edit a fund and click on one of the Planning value (by months, etc.)
The "Fund name" column should be correctly populated with the fund
names.
