Build with code from "Prepend Creation to Title" by Jim and "Capitalize Page Titles" by Omer Atay. Function: Prepend the creation time in yyyymmdd format to titles of pages under selected scope. If the title already has date in other format, such as yy/mm/dd, the old date will be updated to the yyyymmdd format. Note, if the title star with number,"/", or "-", it will be replaced as well.
