Since this was reverted [1], the chromevox tests are failing. Can someone have a look?

I'll take a look. There were at least two reverts that touched the same test. Feel free to disable the failing cursorstest. H

Fix editable text selection

We need to special-case setting selections when the focused node is itself editable.
- make no adjustments for the selected node; placing selection outside of the editable content causes key presses to go to the page
- if we are trying to select the entire node, set the selection index to 0 (placing selection at the beginning of the node); otherwise, use the character offset

TEST=move to a text field or content editable via ChromeVox commands; verify typing works to echo the keys. Furthermore, verify that in a content editable with headings, links, etc, jump commands move the selection. Finally, verify ChromeVox text movement commands (e.g. next character), moves selection in single line editables.
