Get the disposition (attachment or inline) of the MIME part.
The string containing "Content-Disposition" header value, or a null reference (Nothing in Visual Basic) if the part does not have "Content-Disposition" header set.
Examples: "attachment", "INLINE".
If this header is missing, the application should assume "inline" by default.
Note If the entire "Content-Disposition" message header contains some additional parameters (such as "filename"), the developer can examine DispositionParams list to obtain the parameter names and values.
