jlime: Add several small jlime-specific recipes.

jlime: Add several small jlime-specific recipes.

* Added fileselector-1.0, a simple file-selector in C and SDL.

* Added fnkey-1.0, which is used to emulate a Mode_Shift + Shift
  keypress using xdotool on pressing the Fn key. This is mainly for
  the ben-nanonote, and is hackish, but works.

* Added gtk-engine-industrial for gtk-1.2, since we still use gtk-1.2
  applications in jlime, and gtk-1.2 looks ugly by default. This helps.

* Added jlime-extras, a package which adds several files (initscripts,
  configuration files, other support files), some of which replace
  files found in other packages.
