Lower APB ranking requirements

Since we covered this again a few weeks ago I might as well repost some stuff that came up.

KillsPerGame isn't mentioned in this report but it definitely needs to go down, most people who aren't in the top 20 have trouble meeting 4 kills per match and it probably encourages killwhoring. So it could go down to 3 or maybe even 2.5. Another possibility is making it so that "kills" for rank-ups count kills against vehicles as well as kills against infantry; if that can be done, the kills per game count should go up to 5 since vehicles account for about half of units destroyed.

Definitely agreed on reducing ScorePerGame and Games, though I have a different table for games which produces the early results a little earlier so that newbies notice ranks earlier:

0 15 35 60 90 125 165 210 260 320 390 475 575 700 850 1025 1250
