gift to all users on holidays

[vincenzo]

It would be nice if local administration in specific days of giving credits to all users or to users of a single category.

_1 Admin creates the name of the public holiday
_2 Admin decides the number of credits to be given
_3 Admin set which category from the available donate credits
after saving the chat for all users of credit recipients get a message "{website_name}gave you {credit_quantity}.Thanks to be with us"
