Only requiver pickup_thrown ammo and throwing weapons

This is meant to go with commit 3b5634bfba (requiver pickup_thrown
objects if quiver is empty).
Don't highlight swap weapon if not two-weaponing

This makes it easier to tell which of your weapons you're using if
you're playing in a terminal big enough to see the inventory side bar.

NH4: Fix turn usage when applying objects

Many situations and choices when applying tools would cause a turn to be
used when doing nothing, and sometimes even not using any turns when an
action was performed.  This includes fixing C343-353: "Aborting key or
lock pick with escape uses a turn."

Rationale for amended turn consumption rules:

 * Real actions use a turn.
 * Aborted actions do not use a turn.
 * Impossible actions use a turn if the hero attempts them.

Improve consistency of turn usage by doapply(). Fixes at least C343-353.

NH4: Include candles in weight of candelabrum

Fix from GruntHack via NetHack4.

Candles on a candelabrum now have the weight you'd expect. ("Your
candelabrum's flames die. Your movements are now unencumbered.--More--")

NH4: Prevent empty bag of holding weighing more than other sacks

Without this fix, bags of holding weigh 16 when empty while other sacks
only weigh 15, making it trivial to identify bags of holding.

This rounds up the weight of the contents of a bag of holding instead of
just adding 1 and dividing.  May fix C343-418 (bug description is vague
and may refer to gold instead): "Weight of non-cursed bag of holding is
sometimes off by one."

Adjust weight calculation for bags of holding to round up rather than
simply adding 1.
