- Implemented the 'new' NPC skills described here: http://ro.doddlercon.com/wiki/index.php?title=Monster_Skills . It is mostly complete, but the new status changes (slow cast, critical wounds, etc) don't have any visual effects yet (icon or opt changes? I don't know if they should have). Also I could not find the unit_id for Evil Land, so it looks just like Sanctuary for now. Apart from those, the only skills which I couldn't get to display properly are the Breath skills (with the exception of Fire Breath).
- skill_calc_heal now takes the target as argument to properly support Critical Wounds
- battle_calc_return_damage now takes a flag to know if the attack was direct or not, needed since Magic Mirror also reflects indirect attacks.
- cleaned up the 'description' field in skill.c, added skill_get_desc to it
- Removed 'splash' support from Lex Divina as it is no longer needed.
- Modified the way Sight/Sightblaster work so that the skill id is no longer guessed (needed to properly acquire the splash range for Wide Sight)
- Corrected gtb_sc_immunity setting not taking effect if your block value was the same (that is, if the config said 30%, then you would only get status change immunity at 31%, nor 30%)
- Uncommented the 'new' npc skills from mob_skill_db as they are implemented now.
