bless multiple people at once#757

i understand that this was suggested 4 years ago, but i feel like this is a very popular request among frequent mimu users.

blessing is a core part of mimus system, and having the ability to bless multiple people at once would be extremely beneficial, helpful to people who use the system regularly & overall easier and smoother, with less fatigue from consistently doing the /bless @user command.

sorry if this is poorly worded :(
