mapcss: change z-index handling

In contrast to previous default z-index of 1000 for nodes and -1000 for areas, the default z-index is
now always 0. An additional "major-z-index" is used to sort elemstyles by category, this property
can be adjusted in the style, so icons can be rendered below lines, if you want to.
