Implement ggplotly as option

[PhilippPro]

Dear @boxuancui,

this is a nice package.

It would be nice if there would be a default option for producing plotly plots instead of simple ggplot2 plots. Currently you can do this workaround, which is a bit complicated and the output in ggplotly is also not super beautiful, if you hover over the bars:

a <- plot_bar(data)
ggplotly(a[[1]])

It would be nicer if it would be like this with nicer text hover infos:

plot_bar(data, plotly = TRUE)
