Simple mode level setting

[e1q3z9c7]

For now, there's only 4 kinds of options: my level, +-1, +-2, any level, but it's not quite complete. I suggest 5 options: my level, my level and above, my level and under, +-1, any level. (There's only 7 levels so +-2 is almost contain any level). It should fulfill more needed

Well, the idea is that the simple lobby stays simple
For people who want more advanced options, we kept the old lobby where you can select exactly the levels you want for your opponents.
