Title: Doc/pal gradient

Fixed documentation for `gradient_n_pal`. One commit is the minimal fix, correcting the roxygen prefix.
A second commit expands the documentation, and the final is re-roxygenizing.

Note that this commit will ultimately also affect ggplot2's `scale_gradientn.Rd` because that inherits, via roxygen, the description of the parameters from `gradient_n_pal`.
