Split new users into Beginner/Intermediate/Advanced streams

[dexonsmith]

This feature is to split new users into Beginner/Intermediate/Advanced streams. Background in the forum proposal thread.

• New users choose between Beginner, Intermediate, or Advanced.
  • Beginner corresponds to 25k+–12k. The range won't be shown.
  • Intermediate corresponds to 16k–1k. The range is not immediately visible, but is shown if the user hovers or clicks on a ? or something.
  • Advanced corresponds to 4k–9d+. The range is displayed on hover, like Intermediate.
• Depending on the choice, the player is assigned an initial rating of 743 (beginner), 1096 (intermediate), or 1764 (advanced).
  • This is instead of 1500, the old starting rating.
  • Deviation still 350.
  • The rating-to-rank conversion puts that at 22k, 12k, and 2k. (Not advertised to users up front.)
• Stop depressing the effective rank when the deviation is high. (I.e., remove code that made 1500+/-350 act as-if 12k.)

Not quite? We still have the a/b experiment, which I think we can probably decide upon, but we should keep this open until that's settled I'd reckon?
