Title: Add support for timeofday column type and allow javascript types as draw options

Visualizations like the [AnnotatedTimeline](http://code.google.com/apis/chart/interactive/docs/gallery/annotatedtimeline.html) require a Date as one of the options (zoomStartTime, zoomEndTime). I have created a DataCell class to deal with formatting the value to the object that google expects and that class is used to format the values sent to the draw options and the DataTable values.

This pull also adds support for the timeofday type which is returned when a Time object is provided.
