Update 0.2

+ Added some missing onlistens for arrows.  have yet to add onlistens
for arrow kills (have done it for entity arrow kills I think)
+ Restructred some confusing code.
+ (Should Have) fixed the issue with all spawn-points being used when
changing maps.
> Should added more documentation to some of the more obscure methods.
Should also create an overall documentation of how the plugin works.
But that's house cleaning.
