[Frontend] Migrated to s-status-editing

open #199
open #278
Changed CSS to use s-status-editing instead of .active
class;
Refined style defs to explicitly target tree and
search-results children in order to avoid items in
Inspector Elements pool from being designated as
being edited;
Removed {{searchText}} div from input-filter;
