@gradient

@gradient - displays a string formatted with color codes
Usage:
@gradient <xxx>,<xxx>=<string to format>
@gradient/reverse <xxx>,<xxx>=<string to format>

@gradient takes two color code values and a string, then outputs the
string with it changing colors through that range. If the reverse
switch is specified, it will reverse colors halfway through the string.
See @color xterm256 for a list of codes.
