Appending opentip-container elements to a custom element (instead of document.body).

[krisrogers]

I have found that when the tooltip is following the mouse, right on the edge of the viewport, it is possible to cause the body to overflow. Screenshots below demonstrate:

no overflow

overflow

I cannot disable overflow on the body due to the nature of the overall layout. Ideally I would like to see the opentip-container elements optionally added to a custom element (child of body) for which I can set to the viewport dimensions and disable all overflow.

PS - Thanks for easily the best tooltip library I have used!
