Original issue's description:
> Add support for rich output inside of content editables.
>
> This cl attempts to combine output from the editable* and output* modules.
>
> In particular,
> - speech and braille hook into editable for line descriptions
> - additions were made to make cursor selections reflect the current page selection
> for braille
> - a minor change to make braille ignore separator additions when there's
>   whitespace at the end of output. If not, cursor tracking breaks.
>
> What works:
> - earcons, roles, states are now read as you move by line
> - other behaviors (e.g. other unit selections, all text changes) are unaffected.
> - DOM selection changes moves ChromeVox range (e.g. move by word via ctrl+right, ChromeVox range moves with it)
> - ChromeVox range changes moves the DOM selection (e.g. move by heading, by word, line, etc moves the DOM selection there).
