Keyline Icons v0.7.0: Charts, diagrams, faces and square messages

A QR code, scissors in both bodies, an hourglass, a scan frame with six things to read inside it, twenty-six charts, four diagrams, seven faces and a badge with nine signs. And the message family drawn again on a square body, with every sign, badge and slash where the round bubble already puts them.

73 drawings added since 0.6.0, bringing the set to 765.
