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).
Reading the rest of the code, it wasn't obvious to me what the `nativeTooltips.addFOTooltip()`, `nativeTooltips. anchorFO()`, etc. methods were... Until I bumped into this line :)

Not a big deal, but was wondering, is the abbreviation worth it here? Could `addForeignObjectTooltip()` increase clarity?

On a related note, when do you use `addTooltip()` vs. `addFOTooltip()`? Do/could you sometimes use both in the same pool?
