Timothy Flynn 4ab7216827 LibGUI: Use Unicode's text segmentation for traversing word breaks ...

Note that for traversing words with ctrl+(left or right arrow) on the
keyboard, we want to "skip" some boundaries. Consider the text:

    The ("quick") fox can't jump 32.3 feet, right?

Using "|" to denote word break boundaries, we will have:

    |The| |(|"|quick|"|)| |fox| |can't| |jump| |32.3| |feet|,| |right|?|

When starting at "The" and using ctrl+right to move rightward in this
text, it is unlikely that users will want to break at every single one
of those boundaries. Most text editors, for example, will skip from the
end of "The" to the end of "quick", not breaking at the parentheses or
opening quotation marks.

We try to mimic such desired behavior here. It likely isn't perfect, but
we can improve upon it as we find edge cases.
