:clipboard: Server Adjustements

since the follow up on 18 June, several adjustments have to be made to the server to be compliant to the subject. These are as follows:

[x] changes the messages that are sent to all clients that take part to an incantation
[x] update picked_up_items when incantation is done
[x] when a GUI client connects to the server, the server must send the position of all the eggs
[x] handle the end of the game
[x] handle broadcasting on the same tile
[x] forwarding onto another player cause a drum solo in the memory
