Skip Run QSOs on the bandmap and refocus the callsign box after Alt+W

A QSO logged in Run mode is no longer added to the bandmap as a local
spot, including when recent contacts are re-spotted at startup.

Releasing Alt moves focus to the menu bar. Alt+W now sets a flag, and
the Alt key-up handler puts focus back on the callsign box.
