Show "The Unseen Paths" nodes only when allocated (#1742)

* Update PassiveTreeView.lua

* implemented new function

* hiding images from tree

* for connection now check both nodes

there was at least one node connection that wasnt hidden properly.

* comments

* comment

* display unseen path nodes in green when unallocated and hovered over

* fix ascendancy connector coloring

* Fix hovering over hidden nodes

* Add missing centre bit
