Bug 9766 - Remove YUI menu on budget planning page in favor of different column-hiding system

The budget planning table previously used a YUI menu as part of a
system for hiding and showing table columns. Instead of trying
to convert that sytem to Bootstrap I have used code from the
batch modification/deletion pages which uses a list of checkboxes
to show and hide table columns. This has the advantage of giving
the user visual feedback of what columns are hidden and of offering the
user an interface which is familiar from other pages.

This patch also moves CSS from a batch-operations-specific
CSS file into the main CSS file. Batch modification templates have been
modified accordingly.

To test, view the budget planning page and choose different
"plan by" options (by month, by library, by item type). Test
the show/hide action on each individual column and using the
"show all" and "hide all" checkboxes.

Works as described.

This interface is also much more visually appealing, user-friendly, and informative than it was when it used the YUI menu.
