Renamed to PvP Elo, and tweaked for greater compatibility and functionality.

Changes:

• Name changed
  
• Version reverted, to reflect new status
• Commands and permissions renamed
• Config re-vamped
• Added elo-color option
• Changed rating shown next to names in chat to be handled by any chat plugin, using "varElo" variable
  • You will need something like EssentialsXChat to display elo ratings next to usernames in chat

Plans:

• Rework calculation formula to be more fair
• Add tab-autocomplete for command arguments
• Add option for elo in nametag?
