Game server: fixes weight calcs & ensures we aren't recalc'ing player/item stats when we don't need to.
Game server/skill system: the rule to enforce self-skills on the caster is now ignored, as quest NPCs use self-buffs on others (might be better to implement a quest NPC flag for this, rather than allow all NPCs. I don't think it'll harm anything right now though.).
Game server/quest system: implemented Lua binding for GetStat() (original, CheckStatPoint()).
Game server/skill system: fixed a hostility check preventing Descent from behaving with opposite nation party members in neutral zones; resolves #393.
