CSS for .rep-object-label modified; Added CSS class
to tabular-swimlane-cols-tree.html markup;
Also cleaned up .s-status-pending styles for related
label elements;
open #468
Remove ng-class statements in favor of upstream .s-status-editing;
Restructure CSS accordingly;
NOTE: because edit.html has NOT been changed,
changes here will cause old edit mode to no longer display properly.
Don't integrate this CSS with old edit mode!
