This release is the result of a huge porting effort to GIO, and brings
transparent network browsing (ftp/webdav/smb/sftp with ssh-agent/ssh
master socket) through GVfs.
See http://www.xfce.org/documentation/changelogs/4.4.3.
Fixes some bugs which surfaced on amd64 since Glib update, some patches
are now integrated upstream.
While here, update PLISTs and use pkg_subst -c in xfce4-session/Makefile.
