Started working on the command.

Started working on the base of the command, haven't started to add code
for when the player uses the command.
Removed the ChannelType Field

Channels don't seem to be handled by PlayerUtil yet, so I have removed
them and set them as comments.
Updated Save Method

With the new save() method in PlayerUtil, I had to update the save
Method in Nostalgia by getting the PlayerUtils from the players online
and saving everything to the .dat file.
Fixed a message

Under the checkLangYAML() the message of "Cheat.Achievements had a space
in the beginning, it was removed.
