Title: Fix default cc/bcc reset on quick reply

Updated patch of #628.
Your suggestion seems to work fine.

`nsMsgIdentity::Copy` will not copy `doCc` and `doBcc`.

With `popOut`, using new identity causes `from` field empty in new compose window.
It looks not good. So I didn't use new identity if `popOut`.
