A load of refactoring of how content selection and input work.
...
Keypresses now go via content interface.
Contents don't shove the selection object into browser windows any more.
Contents report selection existence by sending message.
HTML content keeps track of where selections in it exist.
Contents report whether they have input focus via caret setting msg.
Caret can be hidden (can still input/paste) or removed.
Consolidate textarea selection handling.
Make textarea report its selection status changes to client.
Various textarea fixes.
Changed how we decide when to clear selections, and give focus.

Calculate and store text offsets only when they change, rather than recalculating on every redraw and caret placement. Also ensures that caret placement and redraw get the same text offset values.

Single line textareas don't have scrollbars, so they don't get the scroll redraw request from the scrollbar callback.

If a character is replaced by a character of different width, the caret needs to move. Checking change in character index isn't enough, so move caret if redraw was required too.
