Adjust tab completion widget if too close to bottom of page.

[ellisonbg]

In master the tab completely widget completely fails if the code is too low on the page and the widget won't fit.

This PR looks to see if the completely widget will fit below the code and if not does the following:

• Inverts the list
• Scrolls to the bottom
• Puts the widget above the code

Here is a screenshot:

It does a pretty good job:

The completer wraps mathjax equation?

I'm wondering about reversing order, muscle memory can be pretty strong.

I am with @Carreau here... you are inverting the order depending on the position of the widget... so sometimes the list is not inverted and sometimes it is inverted... this dual behaviour could be confusing for some people...

Added to the list of topics for the dev meeting...

As discussed in the dev meeting I have removed the completion list inversion.

[Carreau]

You don't invert anymore, you can remove the comment.

[Carreau]

@ellisonbg Do you think you can fix the small comment ? I can also issue another PR with the comment fix, or a PR against your PR.

[ellisonbg]

@Carreau just fixed it, this should be ready to go.

Thanks, merging.
