v0.1.2

Security

• A write was accepted from any other origin on the local network, because the
  origin check ignored the port. It is now exact.

Fixed

• Chord captions contradicted their diagrams: G and D said "Traste 2" while
  being drawn from the nut. Open position now means an open string with the hand
  in the first four frets, a barre is named by its own fret, and the caption and
  the drawing come from one decision.
• A shape with no open strings is no longer called open position.
• An A-shape barre is drawn whole; the window starts at the hand, not the barre.
• A dead inline style in the library, dropped by the content security policy.
