Change selector hash to segregate:

  1) element selectors
  2) universal selectors with class names
  3) universal selectors with ids
  4) universal selectors

Only bother looking for matching selectors in 2 & 3 if the node being selected for has class names or an id, respectively.

In theory, this should speed up style selection somewhat.
