[PROPOSAL] Support for multiple addresses.

I have a request which I'm planning to implement for myself. But would like to discuss it first so it is likelier that this will be merged :).

I'm planning to support multiple recipients input in the backend in receiving mail address form.

example@domain.com;example2@domain.com

Do you like the idea?

Hi, the idea sounds good.

You only have to change the MainController.php file on line 91. (Do an implode on the ; and ',' characters for example, and trim the spaces with the array_map function).

Later on it will of course be better to have something like a button to add a new recipient field.
This will be more client friendly.
Little bit of javascript but if you keep the same field name and add brackets (making the form field an array) then i think it should immediately work as well.
