Updates the arena rating system to use Matchmaker Rating.

Browse Source 
The arena_team_stats sql in this commit sets all ratings to 0.
You start with 0 Team Rating and 1500 Matchmaker Rating.
Personal rating is moved to character_arena_stats, and will not reset when disbanding an arena team.
This new system is based on all the info I could get, but Blizzard didn't leak much info about the new system.
At least this system is really close to the official system.
Any issues found should be reported in an issue.
Huge thanks go to Aokromes for the intensive testing he has done with me.
Also thanks to Parzival for hearing me out and giving his ideas.
Fixes issue #3189
