* skin.dtd: added an attribute "resize" in the "Image" element, to define

  the method used to resize the image, which can be "mosaic" (the default)
  or "scale". Note that the previous behaviour was always "scale" before,
  but mosaic is much much faster, so use scale method only for fun ;)
* skins2/*: support of the new mosaic method; playlist resize with this
  method is significantly faster!
