completer update code-miror on the fly...

completer update code-miror on the fly Following @fperez advice, change the completer apparence to avoid user confusion. - Append what the user type in the completer in code-miror, (Almost) as if codemirror still have focus - distinguish between "fixed" completion part, which was sent to the kernel (now written in bold) and filtering one,handled only in JS,that the user can errase without dismissing the completer I changed the action of <Space> to dismiss the completer with what have already been typed and inserting a space instead of "picking" the currently hilighted option <Escape> will still dissmiss the completer and remove everything the user as typed since the completer invocation Note that while the completer is shown, code-mirror does not show any blinking cursor
