fix text area insertion order, partially

While Leon mulls over how to rewrite WebTextView to
handle webkit driven focus changes, these fixes make
the current code slightly more stable.

Keep track of when keyDown is sent again so that the
WebTextView won't be rebuilt in that case.

Don't clear the cursor from WebTextView if the there's
no native focus pointer.

Only set the selection to its initial state once when
passing events down to webkit.
