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.
