* added hook mechanism to initramfs-init which can be used by plugins

  to trigger execution of their own script at a certain point in the
  initramfs-init execution path. This is not active yet
* added basic implementation outline for Theme (a.k.a splash) plugin -
  unable to test anything, though, as VMware does not seem to provide
  a VESA framebuffer, so splashy won't run
