Improved Selection History (#71) 

* Improved Selection History

* Manage Selection + Highlight / Removed System to simplify explicit references to UnityEngine.Object

* Added Open option for assets (instead of Focus)

* History is now tracked even if window is closed. Opens the window with Alt+H

* Added Object Type to label

* Got rid of Ignore Next Selection
