USCustomary.REVOLUTION_PER_MINUTE wrong name "Pint"

[rloschmann]

    /**
     * Revolutions per minute (abbreviated <code>rpm</code>, RPM, rev/min, r/min, or with the notation min−1) is the number of turns in one minute. It is a unit of rotational speed or the frequency of rotation around a fixed axis.
     * 
 	 * @see <a href="https://en.wikipedia.org/wiki/Revolutions_per_minute"> Wikipedia: Revolutions per minute</a>
     * @since 2.1

    public static final Unit<AngularSpeed> REVOLUTION_PER_MINUTE = addUnit(REVOLUTION.divide(MINUTE), "Pint", "rpm")
    		.asType(AngularSpeed.class);
