How Sleazy Fork will rewrite posted scripts

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

@updateURL and @downloadURL directives will be added or updated to point to Sleazy Fork. @installURL will be removed, if present.
@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.
