Finer interrupt granularity for wait command (#4893).

The wait command now operates by performing up to ten interruptible 1
aut wait delays (still counted as one game turn). They are normally
interrupted by most of the same things as a travel command, with the
major exceptions being seeing or sensing a monster - instead, it is
interrupted by seeing a monster move.

This allows the wait command to be much more useful tactically, as it
will stop waiting at the instant the position of a monster changes
(impacting the tactical situation).

A side effect of this is that the move_nowhere command ('.') waits 1 aut
instead of 10 aut. If this becomes a problem, . could be rebound to the
normal wait command, or a new lower level command could be introduced to
take the place of the current use of the move_nowhere command.

There is a bit of a hack in place to consider 'wait' 1 game turn and
'rest' the same up-to-100 game turns that it currently is (instead of up
to 10 and 1000 respectively). If this becomes problematic, it can easily
be removed.
