New function: sm_print_r()

This is intended to be a debugging function.  Ever wanted to do a print_r, but found that some of the values were "eaten" by your browser's parser because they had <> in them?  Use this function instead.  It runs htmlentities() on the output of print_r() AND as a bonus wraps the entire thing in <pre> and </pre> tags.
