Network manager callbacks

[addonovan]

The NetworkManager class should provide a way to subscribe for the following events:

• connected to a game (on_game_connect)
• disconnected from a game (on_game_disconnect)
• received a card (on_card_received)
• found a game on the network (on_game_discovered)
• a hand ended (on_hand_over)

Each of these subscription methods should have an unsubscription counterpart in the form of unsub_##action_name (e.g. unsub_on_game_connect)
