* Fixed unwrencheable atmos objects' stored pipe being wrongly created on New() because initialize directions weren't set when instanciating
* Fixed constructed unwrencheable atmos objects having a stored straight pipe , because dirs weren't set on instanciation
Those fixes, at least, bend pipes transforming into straight pipes on wrench/unwrench
* Fixed the digital valve pathing in some places
* Fixed bend pipes appearing as straight pipes when wrenched without connecting to anything

* Pipe colors are now preserved on wrenching/unwrenching
* Various clean-up of unaligned partially connected pipes icons
