Merge branch 'master' into CURA-6793_performance

Browse source 
Conflicts:
	cura/Machines/MaterialManager.py -> File was deleted in Master but I changed things for the lazy loading.
	cura/Machines/Models/BaseMaterialsModel.py -> I clarified documentation on a line above a place where a timer was added in between.

Contributes to issue CURA-6793.

# Updating the material model requires information from material nodes and containers. We use a timer here to
# make sure that an update function call will not be directly invoked by an event. Because the triggered event
# can be caused in the middle of a XMLMaterial loading, and the material container we try to find may not be
# in the system yet. This will cause an infinite recursion of (1) trying to load a material, (2) trying to
# update the material model, (3) cannot find the material container, load it, (4) repeat #1.
