Title: Make highlight background configurable

Background color and animation while highlighting series
is now configurable using these options and defaults:
- highlightSeriesBackgroundAnim: true
- highlightSeriesBackgroundColorRGB: '255, 255, 255'

Updated dygraph-options-reference.js

Needed this for my project and thought it would be a good thing in general.
