remaining native SVG tooltips

Native SVG smbg and bolus/wizard tooltips.

@ianjorgensen can you take a quick look? Would like to merge this today (and work through merge conflicts with @nicolashery while merging in his new workflow branch).
Same comment as `onday.js`, did you want to remove `tooltips`? Also, you didn't remove `container.tooltips()`, but you did in `onday`. Are you still using it here?
