+	* Added function battle_calc_gvg_damage for gvg related damage reductions.

+	  Fixes Gravitation being reduced as well as Pressure overriding max-castles

+	  restriction. [Skotlex]

 	* Corrected char-server parameters so that the subnet config file is the

 	  third parameter, not the second (which was conflicting with

 	  inter_athena.conf's argument), thanks to foobar. [Skotlex]
