Support selection and copying over non-editable content in ChromeVox Next.

Support selection and copying over non-editable content in ChromeVox Next.

What works:
- search+s toggles on / off a DOM-based selection
- selection by character, word, line, object work across multiple nodes*
- announcement of what gets read via a clipboard hack
- ctrl+c is observed and reads out copy events in lue of an actual copy event in the DOM (we're at a disadvantage here)

*works currently for basic examples. The underlying "framework" fails in slightly more complex cases like a paragraph with a link in it or a line break. For example, a link followed by a static text fails when attempting to select the static text via index offsets. Likely a Blink issue.
