LPS-44220 - Display save button in add members only when there is a large number of results to display

Hey @mmoegelin,

Attached is an update for http://issues.liferay.com/browse/LPS-44220.  We need to update this pull request to move the numerical value in /portal/portal-web/docroot/html/taglib/ui/search_iterator/page.jsp  into a portal.properties setting and reference this value in the portlet jsp file.

Please let me know if you have any questions.  Thanks!
