VERY experimental commit:

shared SelectFeature control for WFS and geometryLayer data

getting rid of ooi_click endpoint. Instead, a 'clicked' endpoint transmits lon-lat data including either an 'ooi' or 'area' property depending on whether something was hit on the geometry or WFS layer. If neither is present, nothing was clicked but a blank spot on the map.
Minor cosmetic fixes
Childs for selected groups in OOI table now visibly highlighted

OOI table now "remembers" what was grouped and selected when setOOIs is invoked, so it can restore this data
