Allow unsetting a gnuplot variable

This change adds a method Gnuplot::Plot.unset(var) to unset the Gnuplot variable var. As
the order of sets and unsets are important for Gnuplot, a new array "settings" was
introduced in which the set and unset tasks are accumulated.
Corrected the labels in the second example of README.textile
