>Replaced dd_text2list, dd_text2listcase, tg_text2listcase and tg_text2list with text2list and text2listEx. text2list will return a list of each and every character in the string if you set separator=""
>added return_file_text(filepath) which returns text from a file after doing some checks: does the file exist? is the file empty? It prints helpful error messages to the world.log if it runs into problems
>Replaced dd_file2list(filepath, seperator) with file2list(filepath, seperator). It just calls text2list(return_file_text(filepath), seperator). rather than copypasta
>Replaced time_stamp() so it's not as retarded
>Lots of the world setup stuff uses file2list now, rather than file2text -> sanity -> text2list
>Added error() warning() testing() procs. These print messages to world.log with a prefix. e.g. ## ERROR: msg.
