Bug: WebApplication.SendStream remove .txt extension

[RenSword]

When I try to use 

Code:

WebApplication.SendStream(M, True, TIWMimeTypes.GetAsString(mtTXT), 'testing.txt');

to send text file with SendStream, it remove my .txt extension, if the filename is .xml or etc, it has no issue.

To replay, can try run the sample project and press the button. testing without .txt file extension will be downloaded.
