banner: give the bit actual teeth

Previous staircase pattern was just trailing decoration — not real
key teeth. Redesigned the bit as a hanging rectangle with two
clearly-projecting notch-teeth on its right edge (the part that
engages a lock's wards). Switched to box-drawing chars for the bit
since they make sharper notches than 8/b/d glyphs; bow stays
ornate-ASCII style.

Bump 0.4.3 → 0.4.4.
