Pull request from entrez: the log message "hit with a wielded weapon
for first time" for breaking the "never hit with a wielded weapon"
conduct wss being given when hitting with wielded non-weapons. Since
the conduct remained unbroken in that situation, the 'first hit'
message would be re-logged for subsequent non-weapon hits. This bug
was not present in initial livelog implementation; it was introduced
by the change to log first-hit before first-kill when those occurred
on the same attack. Verify that the wielded object is actually a
weapon or weapon-tool when deciding whether to log first-hit event.
Closes #708
rearranging first-kill and first-hit gamelog messages to get hit before kill
ordering resulted in "hit with a wielded weapon for first time" being
given twice if that hit was delivered via applied polearm
