Welcome XFCE 4.14 to the FreeBSD ports tree

- This XFCE release uses almost exclusively gtk3, so the USES=xfce
  now defaults to gtk3
- Make x11-themes/gtk-xfce-engine an optional dependency(disabled
  by default), it only supports gtk2, so would leave miost of this
  XFCE version unthemed.
- Add Greybird as an optional and enabled dependency as a modern
  theme supporting both GTK versions and all other XFCE parts
- The xfce4-vala port is deprecated and removed. The VALA bindings
  are available in the library ports using the GIR and VAPI options
  (on by default)
- Fixed various missing library and portlint warnings (portmgr fixit
  blanket)
- Default Display Manager changed to lightdm (Thanks to woodsb02

- Simplify XFCE MASTER_SITES usage
- Update XFCE Master sites list
