How Greasy Fork will rewrite posted scripts

Scripts posted to Greasy Fork will be rewritten in the following ways:

@updateURL, @installURL, and @downloadURL directives will be stripped, if present. The lack of these directives means that any script installed from Greasy Fork will be updated from Greasy Fork.
@version and @namespace directives will be inserted if the script is missing them. These directives are needed for proper updating.
@description will be inserted if a new version of a script is missing it and a previous version of the script had it.
CRLF and CR line breaks will be converted to standard/Unix-style line breaks.
