will result in a InvocationTargetException now with a getCause(),
which gets handled as if that exception was thrown from the actual
Method that is invoked for the command.
Cleaned up InvalidUsageException and CommandException to be less confusing.
Removed gold color from CommandUsageBox for command help.
Added "Usage: " back when handling InvalidUsageException.
When sorting commands for //help, ignore / characters.
Sort commands for Dispatchers in CommandUsageBox.
