Added notification message on Join when global xp boost is active (can be disabled)
Added new command /xpboost global <boost>, which changes current global xpboost multiplier
Added ability to change an item type in config of an item which is being given thorough /xpboost item command
You are able to give a boost to everyone by using /xpboost give all
You can assign which XP will be affected in the /xpboost give command /xpboost give <name/all> <boost> <time> [vanilla,skillapi,mcmmo,rpgme,heroes] (eg. /xpb give all 2.0 300 vanilla,skillapi <- this will give boost to everyone which will affect only vanilla & skillapi experience)
Added Heroes support
I recommend to regenerate your config to get all required comments about new features.
