Changes:

• New elo calculation formula. Check the documentation.
• New, better aliases. Old aliases are still there, but "elo" and "eloa" are now available for ease of use.

Plans:

• Tab-autocomplete for command arguments
• Elo shown in nametag option

With these features, I will consider it functionally complete for a 1.0 release. Please let me know what other features you would like to see!
