a bit of freebsd support
convert to double before anything

vector field plotting
Less annoying messages

Update index.dok

Added <Use an empty string (2 apostophes in a row) if you want to keep the current value.> for keeping the current value of {xmin,xmax,ymin,ymax} in <gnuplot.axis> documentation. Actually, I don't know how to write the <''>, since these are a command in the documentation..
add documentation for gnuplot custom string
