Bug 33662: Add link to acq advanced search to acq navigation

Right now 3 clicks are needed to open the advanced search page
in the acquisitions module.

This adds a link to the advanced search to the left hand
module navigation.

To test:
* Go to acquisitions
* Verify the way is long to advanced search:
  At the top: Orders search > config icon > advanced search link
* Apply patch
* Notice new 'Order search' link on the left
* Verify it's way shorter now :)
