Outliner: Allow select on row icons
Allow selection of subtree elements on a collapsed element's row. Because subtree elements are aggregated by type, a select on an icon that represents multiple subtree elements will invoke a popup menu to select the specific subtree element. Also draws highlights on cursor hover over a row icon. Any child elements that are linked to multiple collections will only be listed in the popup one time, and selection from the popup will select the first instance in the subtree.
