Title: Added options for reference lines in line-charts.

Added options for refLineX and refLineY which draws a reference
(horizontal/vertical) at corresponding X or Y value - in the color
specified by the option refLineColor (with default value).

Mostly to scratch my own itch. Who ever shares my itch, please help yourself.
