Make Player::peer_id server-side only and add getters and setters (#6478)

Browse Source 
* Make Player::peer_id server-side only and add getters and setters

Player::peer_id has no sense client side, move it to server, make it private and add setter and getter
Also add some PEER_ID_INEXISTENT instead of harcoded 0
