Add parameters to the bokeh hover object and functionality to the coffeescript layer to dispaly formatted strings in the hover tooltip divs. Strings are stored in a specified column of the plot object columnar datsource. Also accept a dict of CSS style properties that are applied to the tooltip div. Currently accepts text and backgroun color properties. Also some logic so that missing or nan data are not displayed in the tooltip divs.
Expose the load_from_config bool as an argument of output_server() so that this parameter can be readily accessed when using bokeh-server
