Bug 26497: "Hide all columns" throws Javascript error on aqplan.pl

This patch updates the JavaScript for checking and unchecking checkboxes
on the Acquisitions planning page so that it doesn't require the
checkboxes plugin.

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

On the planning page, test the "Show all columns" and "Hide all columns"
checkboxes. They should work correctly to show and hide the correct
columns.
