Major overhaul, big changes.

So this previously simple plugin got a bit more complicated. But not more complicated to use! It will actually be easier to use! :D

I added an auto nerf that will ensure the players that join the party are less likely to overtake the main characters level. As long as you set the multiplier to a reasonable level and turn the plugin features off for boss fights or other battles that give large amounts of experience, it should be easy to balance.  I've added suggested defaults multipliers that have worked pretty well in testing. 

Speaking of turning plugin features off, I added the ability to specify a switch in the parameters that you can turn on to disable the plugin features as you wish. This is, again highly recommended for boss battles! :D

I hope you guys like the changes. I think part of my brain leaked out of my ear when I was trying to figure out the math lol.
