Title: New option "zoomRectColor"

This option allows it to set the color and the transparency for the zoom selection.
Based on the option "gridLineColor" this option uses directly a string (e.g. "rgba(255,255,255,0.5)"). The default value has been maintained and set in the default option section in the dygraph file. Additionally a demo has been added in test folder (zoom-color.html).
