Implemented print preview

Created function ephy_web_view_show_print_preview, which replaces the
old implementation of print preview, which was not working now.
Preview is displayed in an external viewer, so print preview mode does
no longer exist.

All functions of the old implementation of print preview have been
removed, PPViewToolbar was removed also.  Also, as EphyWebView has no
more a print preview mode, all functions which checked if a view was
in print preview mode were modified.
