Allow entering multiple recipients for one form of notifications

[johannesE]

Hi there, I would like to either configure multiple addresses like this:

"notifications":{
	"mail":{
		"smtpHost":"smtp.gmail.com",
		"port":587,
		"username":"yourmailid@gmail.com",
		"password":"your gmail password",
		"from":"yourmailid@gmail.com",
		"to":"destemailid@gmail.com"
	},
	"mail":{
		"smtpHost":"smtp.gmail.com",
		"port":587,
		"username":"yourmailid@gmail.com",
		"password":"your gmail password",
		"from":"yourmailid@gmail.com",
		"to":"destemailid@gmail.com"
	}
},

Or be able to use an array in the to field.

Also, while I'm bothering you with feature requests: a bcc would not hurt ;-)
