Change the bash value and to-hit of several items

Nothing big, just some values change that was bother me for a while.

Noticable change that will affect gameplay:
+ Quarterstaffs are weaker now
+ Buffed mace and morningstar
A slight nerf, yes. This is in relation with full-on bashing weapon (mace and the likes) and to have a smaller bash value compare to upgraded bats (barbed and nail variant)
