adds the function template::adp_include which is a public interface for generating strings from adp includes instead of the private template::adp_parse -string; also docs for template::util::multirow_foreach
Reverting to version 1.30, moving new adp-revealing developer support code to tag-init.tcl where the checks run more efficiently (once per thread after startup instead of once per view per template ) and the inserted markup doesn't break the DOM.
