EQEmulator Forums - COMMITTED: Slow Mitigation

As requested, I have setup slow mitigation for mobs. I felt bad last time I submitted and Derision had to go back and change a bunch of things, so I made sure everything looked a lot cleaner this time. I have also been studying the emu code a bit more, so hopefully this submission doesn't need any changes.

~~Fully tested. Compiled and works in game.~~

How it works: Mobs have a new added column under npc_types that is a float. 0 = 0%, 1 = 100%, .5 = 50%, etc. With the way the code currently is, if you try to go past 100%, it will default to 100. However, this can easily be changed for anyone who wants to say, penalize a party for trying to slow a mob by hasting it instead. And for those that are worried, this defaults to 0 for all NPCs unless you change it in the database. *Pokes Trev*
