Differentiate between monster anger from attacks and from other causes

setmangry() and wakeup() were being used for multiple purposes. Add an
extra parameter to track which. This fixes several minor bugs (e.g.
whether monsters with no eyes were angered by (useless) gaze attacks
against them previously depended on the state of a UI option, and
the Minetown guards would be annoyed if you used a cursed scroll of
tame monster on a shopkeeper). It's also a prerequisite for the
Elbereth changes I'm working on.
