CoinRankDisplay nga Marshall

This addon will automatically display a player's coinrank next to their name in Challonge. It will also display the estimated change in coinrank for winning a match.

Note:: The estiamted coinrank change feature is a work in progress. It is also an estimation because:
1. I cannot know a player's variance value and thus cannot truly calculate trueskill value
2. A player's coinrank changes with every match they play. It's possible someobdy's rank has changed significantly since the last update.

Please keep these features in mind when using the addon.
