Fixed issue 05317: templatereplace() doesn't properly handle some missing replacement values
Dev moved templatereplace, instertAnsReplace, and tokenReplace into replacements.php
Dev refactored templatereplace to first assign all replacement values to an array, then do all replacements in one loop
Dev rather than via multiple in-line str_replace() functions
Dev note - this version has several variables not in main branch: AID, GID, QID, QUESTION
