Bug 27653: Use div instead of caption for controls

The funds and acquisitions home page tables use captions for additional
table controls. These are more appropriate as "toolbar" divs.

This patch converts the <caption> to <div class="toolbar btn-toolbar">
and moves it just above <table> in the markup to keep it valid.

To test:
1 - View the tables on acquisitions home and budgets views
2 - Note the 'Expand all...' control row
3 - Apply patch
4 - The row remains, but is below the table controls
5 - The row is not included when printing or copying the table
