Add test for SimpleCharprefixTree.
Changes for command lists, opinconsoleonly -> consoleonly.

The command lists for handleaschat and exclusions are now also fed with
 a leading "/" if missing. Allows more convenient setup and less 
 confusion potential for relating comamnd lists in "protect plugins" to 
 other lists.
 
opinconsoleonly has been made a list of commands:
	protection.commands.consoleonly.
Further the message sent to the player is the permission message,
 if the player does not have permission to use the command,
 provided NCP can find the command.

All three command lists are also checked with the original 
command label.
