Merge branch 'libArachne_rebased'

Conflicts:
	plugins/SimulationView/SimulationPass.py -> Reverted layer view optimisation in Master while some whitespace changed in Arachne.
	resources/definitions -> Bunch of conflicts with profile updates.
	resources/quality -> Bunch of conflicts with profile updates.
	resources/texts/change_log.txt -> Removed the Arachne change log (as they are internal versions). It'll have to be re-added when we release this version as stable.
