Title: Removing remaining documentation referrences to reshape

ggpcp stated it was using reshape::melt, but it is actually
using reshape2::melt.

The scale arguments to ggorder and ggstructure had a scale
argument that was no longer used (corresponding argument in
ggpcp removed in 030fadf59a0fd896865b28fd9e76da9698164ec2.
Removed this argument (and its documentation which referenced
reshape).

Since I didn't have reshape installed on my newest R installation, these references were generating a NOTE in R CMD check for me. Since ggplot2 doesn't rely on reshape, but rather reshape2, now, I figured I would hunt down the source.
