org-plot: Respect parameters given in `org-plot/preset-plot-types'
* org-plot.el (org-plot/gnuplot-script-preamble) (org-plot/gnuplot-term-extra): Explain what "plot type" means. (org-plot/preset-plot-types): Fix docstring and correct the lambda argument order for the 'grid' plot type. (org-plot/gnuplot): Merge the parameters given in `org-plot/preset-plot-types' and the #+PLOT line to ensure the former is respected everywhere.
