 * ggplotly() now supports most of scale_*()/theme()/guides().

In order to support all of scale_x_*() an scale_y_*(), we always use linear axis types, and supply ticktext/tickvals to plotly.js. This has some unfortunate consequences on hoverformatting, which may be addressed in future releases of plotly.js -- https://github.com/plotly/plotly.js/issues/320
