Bug 36885: Fix Bootstrap tooltip on budget planning page

This patch finishes the process of adding a Bootstrap tooltip to the
listing of funds which are locked.

To test, apply the patch and go to Administration -> Budgets.

- Edit a budget and make it locked: Check the "Lock budget" checkbox and
  save.
- View the budget you locked.
- From the toolbar, click Planning -> Plan by months.
- In the table of funds, hover your mouse over a fund.
- You should see a Bootstrap-styled tooltip, "Fund locked."
