Online Name-Completion

If a component of RoyalCommands states that it supports online name-completion, then it will allow for a name argument to be partially completed when entered; the name will complete itself if a player matching it is online.

Examples

The following people are online:

Notch jeb_ deadmau5
jkcclemens WizardCM Honeydew
Xephos Dinnerbone EvilSeph
/tp d Will complete to either deadmau5 or Dinnerbone, most likely depending on login order.
/tp di Will complete to Dinnerbone.
/tp de Will complete to deadmau5.
/tp j Will complete to either jeb_ or jkcclemens, yet again depending on login order.
/tp jk Will complete to jkcclemens.
/tp je Will complete to jeb_.
/tp jeb_ Will not complete (already a full name).
