Fix Waymarks!

Very minor nagging. None of these ever held anyone back. But make it better just for the sake of making it better?

1) Change B/2 to green, from yellow. (Controversial!)

Reason: "The Minstrel's Ballad: Tsukuyomi's Pain" has simple role cleaves and role meteors. DPS to go to A/1 because they're red. Tanks go to C/3 because they're blue. And healers go to B/2 because they're yellow. Obviously.

2) Add E/F waymarks. (New colors: brown and pink)

Reason: 48 player content exists

3) Add 5/6/7/8 waymarks. (Mirror the colors from 1-4.)

Reason: Would be slightly more clear for Arkveld's limit cut.

Do not allow more than 8 waymarks. Currently there are only 8 waymarks and each can be placed once. My suggestion would add more options, but attempting to place a 9th waymark should produce an error. You choose which eight to use.
