BIM: Hide all objects that aren't selected during Isolate

Browse Source 
Currently if user selects an item and does `Isolate` operation on it in
BIM, everything is being hidden if the item was inside another container
(like Building).

This is because we are prioritizing on hiding parents of current object
if they are not the selected ones, which is causing the child of the
parent to be hidden as well (duh).

So, this patch fixes isolate method to hide all other parents and their
childs. If they are not a parent of our child under selection -> hide
them and proceed further. If we are processing parent of our selection,
just hide anything on current level that is not our selection while
leaving parent intact.
