- &upload_embedded() moved from portfolio.pm to loncommon.pm to be more widely available.
- &check_for_upload() to prevent overwriting of existing files with uploaded embedded objects moved from portfolio.pm to loncommon.pm.
- &suppress_embed_prompt() added to allow course-wide suppression of embedded object checking for uploded web pages for students in course context.
- checkbox added to allow users to opt out of embedded object checking when uploading web pages to portfolio (default is to check).
