Download builder produces js with missing metadata in comment

Example:

/*
 @product.name@ JS v@product.version@ (@product.date@)

Also inside generated SVG you can see:

<desc>Created with @product.name@ @product.version@<desc>

Thanks for reporting! We'll replace these variables with meaningful information.
