Acq: change a FilteringSelect dijit to a regular <select> to avoid a
manifestation  of Dojo bug #11062; add more refresh grid buttons to unified
search

"Refresh Grid" buttons are a sad little stopgap measure to address a problem
where some AutoGrids show only some of the rows they're supposed to. Calling
.refresh() on the AutoGrid consitently right the grid.  Maybe the problem
is some kind of race condition, and maybe it's related to the use of "get"
and "formatter" attributes for some columns.  Or maybe it's something else.
Attempts continue to find the root of the problem and repair it.
