Sparse 1.05b released

A significant new release, which introduces some changes that are not compatible with previous versions. Upgrading isn't hard, don't worry! New features include a support for sorting data and for printing out the number of results, further useful attributes for quick templates, and a "tag referencing" system which acts similar to CSS classes in that it allows you to reuse attributes from previous tags, or to import them entirely from a separate page. You can define default attributes for all tags as well as "classes" of attributes. As usual, testers are needed!
