Make directory for XFCE backgrounds

- Update branding for Seven platform

- xfce settings: Set ristretto as default images viewer.
- Replace gnome-mplayer with smplayer.
- system-settings: Add comment about requires.
- menu: Use 'xfce-applications-merged' directory only.
- system-settings Add workaround for 'lightdm cursor' bug.
- indexhtml: Fix title in the Russian index.html.

Place whole menu as single menu-file in
the xfce-applications-merged/ directory.
Don't use applications-merged: it is broken in the
altlinux-freedesktop-menu-0.65-alt1.
See ALT bug #29129 for details.

See https://bugzilla.altlinux.org/show_bug.cgi?id=29167
for more information.

So it will be better looking if STATUS is %nil.

Package polkit rule for NM in the separate subpackage.

Add polkit rule for this.

GPLv2+ instead of GPL.

- menu: Fix GenericName of winefile.

- xfce settings: Disable GNOME compatibility mode.

This means to launch gnome-keyring only and using it as
ssh and gpg agents is not good idea. Gnome-keyring as the
secret agent will be launched via DBUS still,

- Fix license.ru.html.

~/.fonts.conf.d is deprecated, should be used
${XDG_CONFIG_HOME}/fontconfig/fonts.conf instead.
