misc...
* regular gtk search in entity inspector -> entity class list
* fix: entities, converted to ( targeted + having model + not loaded b4 ) ones weren't selectable normally + rendered only while 0 0 0 was visible
* ExpandSelectionToEntities works, if only parent node is selected, too (via entity list)
* Select & normalize color commands work for group ents, if contained primitive is selected
* remove boolean key, if set via entity inspector checkbox to 0 (ex: light - sun checkbox: was _sun 0, if off)
