Bug 22556: Add ability to quickly filter funds/budgets by library on the Acquisitions home page

Some librarians would like to have a quick pulldown selector to filter budgets and funds by library on the acquisitions home page.

Test Plan:
1) Apply this patch
2) Navigate to the Acquisitions home page
3) Notice the new pulldown on the budgets table labeled "Filter by library"
4) Select a library that has one or more budgets/funds
5) Note only budgets/funds from that library now display!
