Fixed issue where uploading PSDs with a MIME type of either image/psd or image/vnd.adobe.photoshop would result in the file icon only showing a spinner and the upload not completing.
Added "Update URI" to plugin header to improve security.
Fixed issue where rehydration info would be output for any File Upload Field rather than ones using File Upload Pro which could cause PHP errors in some situations.
Fixed JavaScript conflict that could occur in the Full Site Editor in WordPress 5.9 Beta.
