Open type hierarchy from Type Hierarchy editor

Browse Source 
Make it possible to open type hierarchy for different
class selected from Type Hierarchy editor.
Make it available under context menu or on double click
on class name (single click opens the class in cpp editor window
as before). Double click doesn't expand / collapse items anymore
(expanding available when pressing the visual arrow).
Make navigation to editor more up to date - e.g. when linked location
changed in meantime (source file was edited), it tries to find
linked symbol quickly again (we introduce a small delay, up to
100-200 ms, depending on source file).
