Fix PVP Bow damage

[kphoenix137]

Wasn't sure how to write a title for this one. The player's base damage while holding a bow is modified by cutting the base player damage in half if the hero is not a Rogue. This applies to the character panel damage, and against monsters. The code for this is missing in the Plr2PlrMHit() function, causing no base damage reduction for non-Rogue heroes. There is no evidence that this is an oversight other than speculation, however I believe this adds consistency. There is also no evidence in favor of no damage reduction for PVP, as this is only a result of missing code, and there is no code that deliberately gives more damage to non-Rogue heroes in PVP.

I have no idea what's going on here :')
