Add Dynamic Group Setting - Returning attacks and Returning support

I apologize if this was already submitted in https://forum.tribalwars.net/index....ps-based-on-returning-outgoing-troops.286510/ but I wasn't sure since that one seems to have it as a "secondary wish".

I suggest to add "Returning attack" and "Returning support" settings with the same options as "Outgoing attack" and "Outgoing support" shown in the following picture:

I'll approve it under the same and mention it in that suggestion.
