Qt tombstone bugs

Browse Source 
Infrastructure bits:  Qt tombstone uses a short buffer; make sure that
the plname value fits instead of relying on snprintf() to truncate it.
A warning about gold, if any, was iffy but this should guarantee no
reason for future complaint.  Year was safe but a compiler sensitive
to buffer overflows wouldn't know that.

Actual bugs:  Qt used money in inventory for gold amount on tombstone;
that overlooks gold in containers and will be 0 by tombstone stage if
bones get saved.  Year was recalculated from current date+time instead
of using the value that gets passed in--blindly flagging that variable
as UNUSED was a mistake.

first active light source in a previously unused slot on lower right;
show first leash-in-use in a previously unused slot on lower left
Qt: paper doll inventory view was inconsistently updated during Hallucination
Qt: when hero died, gold on tombstone only included gold in inventory, not
any additional gold inside carried containers; also, inventory gold
will be zero if bones get created for all 3.6.x and for 3.4.x+GOLDOBJ
Qt: tombstone showed newly constructed date instead of the value set up at
time of death; it only shows year but that could be wrong if player
stared at or ignored prior --More-- for long enough on 31 December
Qt+QSX: fix control key
Qt+OSX: rename menu entry "nethack->Preferences..." for invoking nethack's
'O' command to "Game->Run-time options" and entry "Game->Qt settings"
