Update PageFinder to support OR-group selectors. To use, surround a selector string in parenthesis, within another selector string. Example: "template=product, in_stock>0, (featured_from<=today, featured_to>=today), (highlighted=1)" --that selector would find all "product" pages that were in stock, and were either fell in a featured date range, or had a highlighted checkbox checked. This is something you couldn't previously do with selectors. You can also name your OR conditions if you want to have different combinations of them by specifying "foo=(selector), bar=(another selector), foo=(yet another selector), bar=(and another)", replacing "foo" and "bar" with names of your choice (this is not a field name, just a means of grouping). In that selector, at least one of the "foo" named selectors would have to match, and at least one of the "bar" named selectors would have to match.
