fix #H1816 - polearm/grapnel/whip fixes (trunk only)

Browse Source 
From a bug report, applying a polearm to make a
short-range ranged attack didn't scuff any engraving you were standing on,
unlike ordinary melee and throwing/shooting attacks.  Grappling hooks had
the same omission.  Fixing it led to several other minor bugs.  Attempting
to target an unseen monster's spot with polearm or grapnel would yield some
permutation of "wait, there's something there" but draw the 'I' glyph at
the wrong spot.  It used <u.ux+u.dx,u.uy+u.dy> instead of the actual target,
so put the 'I' one step in front of your most recent move (or throw or zap
or whatever last set u.dx and u.dy).  Giving ESC when prompted for target
spot failed to use up a turn even when the polearm or grappling hook had
just been auto-wielded for use.  Neither use_pole() nor use_grapple() set
`notonhead' for hmon() (called via thitmonst() in their cases; this was
academic since plain physical damage attacks don't actually care about it).
[The bad 'I' placement was a post-3.4.3 bug.]

     Applying a bullwhip to attack an adjacent monster didn't have any of
those issues but did have the possibility of targetting off the edge of
the map when standing at that edge while confused or stunned.

     Applying a polearm to target an 'I' would yield "nothing happens" if
the unseen monster wasn't there anymore, and it didn't bother to remove
that 'I' from the map.  After changing it to do so, the phrasing no longer
made any sense.  This led to a slightly bigger change than I intended:
since statues are now shown as gray monsters (does that work for tiles?)
instead of as chunks of stone, they are likely to be intentional targets
sometimes, so polearm attacks now handle them differently from other
non-monster locations.  [I hope that other attack forms don't need
similar handling.  Melee certainly doesn't, since walking onto the spot
is enough to distinguish statues from monsters.  Having the missile pass
right through a statue's location probably suffices for ranged attacks.]
