A nicer "show" action is possible.
We want to show filters on index and trash
Seems that this is no longer used.
Highlight current selected filter
:nail_polish:
Properly set the action glyphicon
Set glyphicon for "Restore" and "Delete Permanently"
Instead of rescue we now have a default value for the glyphicon.
Consistency for the "Destroy" glyphicon
Use the caret to display order direction.
