Bug 34805: Add order search form to acq start page

This patch adds the order search form to the Acquisitions home page.
I've modified acqui-home.pl so that it will pass the same default date
limiters as histsearch.pl.

To test, apply the patch and go to Acquisitions.

Test the order search form to confirm that it works as expected. Any
search from this version of the form should return identical results to
seraches performed from the "Advanced search" link in the sidebar.
