hero_seq

'moves' is actually turns and there hasn't been any straightforward
way to track actual hero moves.  Add hero_seq for that.  It isn't a
counter but is distinct each time the hero makes a move.  I wanted
it for curses ^P support but so far use it for checking stethoscope
usage and for shopkeeper behavior when items in a shop are broken by
the hero.

Increment EDITLEVEL due to change in save file contents.
