open #468
Removed ng-show="editMode" in object-inspector.html;
Refactored CSS as required in _inspector.scss;
Added opacity transition to splitter-inspect-panel and
split-pane-component pane bottom, but not working as desired currently:
entire inspector seems to be destroyed and recreated when switching into
and out of edit mode;
Moved <style> def for .location-item in object-inspector.html into .scss;
