Updates schedule, vacations and a slight delay

In the last update notes I said: "If all goes well, the next update will reveal the whole new leaderboard in all of its glory" Well, all didn't go well :) I mean, technically it was working, but it generated a lot of behind the scenes web api calls that were not really necessary, and introduced some delays in the leaderboard updates. So after days of testing I scratched that and coded an alternate mechanism for the monthly leaderboard. Also, I introduced a way for players to challenge in-game friends to a multiplayer match, instead of trying to find a random opponent. I'm currently putting the last finishing touches on this feature, then it will need some more testing. In addition to all of the above, tomorrow I'm leaving for a week of vacation, so I decided not to release any updates this week, since in the next days I won't be ablo to fix things quickly should anything go south with the new features. So, the next update should be released some time in the week after the next one. See you in a few days!
