Subject: [PATCH] Fall back to different quality depending on stack

Falling back to normal.inst.cfg isn't enough. That profile may be filtered out by the machine, variant and material. We need to fall back to a different quality profile depending on the machine, variant and material.

Contributes to issue CURA-844.
