LP#1746566: Enable 500, 1K, and ALL-the-Rows in patron grids

This adds to the Patron (non-catalogued) Items Out, Patron Holds, and
Item Status grids an 'allowAll' grid feature which will enable the 500,
1K, and ALL (really 10K) rows/pagesize. For the ALL option a modal has
been wired to that the action can be confirmed, since it might be a
very slow operation.
