Changing search field from idinfo/keywords/theme/placekey to placekey
limit searching to "common" fields that are indexed.include checkbox to search all fields.see bug #3174
handle special case for searching both SANParks and SAEON (but not all of KNB)
use keyword for restricting the search by node
