* This rewrite allows for better adaptation from the Aegis Class and Attribute fields.
* Refactored the renewal level penalty function.
* Slaves are now properly assigned an official slave mode of CanWalk, CanAttack, and NoRandomWalk.
* Removed extra Boss checks and adjusted others to use their proper functions.
* Properly implemented Skill Immunity mode to match Aegis.
* Separated MVP and Boss modes.
-- MVP mode defines when mobs should give MEXP, MVP Drops, and show the MVP sign.
-- MVP now have their own item drop configurations.
* Updated the mob_db and mob_skill_db to match the new mode structure.
-- Included a Perl tool (tools/convert_monstermode.pl) to allow people to convert their custom mobs to the new mode structure.
Thanks to @Playtester and @Lemongrass3110 for help with debugging and information!
