ACQ : Support lineitem fucus in ACQ unified search

Adds support for a "focus_li" URL parameter to ACQ unified search
results pages.  When present, the page of results containing the
requested lineitem are loaded (instead of the default page 1) and the
lineitem is made visible in the viewable screen using the lineitem table
focusLi mechanism.
