NEW: Script can now gather data from token entry and use that data in…

… presenting questions. New function "getTokenData" which returns an array containing the token info. New "str_replace" lines in templatereplace function to replace {TOKEN:FIRSTNAME} etc.. with that data if it exists. Modified buildsurveysession() function to add $_SESSION['thistoken'] variable if the survey uses tokens and is NOT anonymous.
