   1 # Functionality:
   2 On Game page "mconnect" events =>
   3   send lastate to them (because they have the game infos) or just "your turn" - if their turn
   4   remember them to send next "newmove" (or just "it's your turn") later - if not their turn
   5   (=> listen for "mdisconnect" as well)
   6 From MyGames page: send "mconnect" to all online players (me included: potential multi-tabs)
   7   When quit, send mdisconnect (relayed by server if no other MyGames tab).
   8 And remove current "notify through newmove" on server in sockets.js
