Subject: With or without multiview, a crash can happen randomly if the statusbar timer times...

With or without multiview, a crash can happen randomly if the statusbar timer times out after the view is closed. Two reason for that:
1) LyXFunc::lyx_view_ is not set to 0
2) quiting is not set to true.

This patch add safe guards when closing a view and/or exiting.
