Description

Especially on Windows file extensions are very handy, if you give the output files the `eml` extension you can just double click the file to open the mail in outlook.

I have added a `FileExtension` option to the `SmtpPickupDirAppender` that can be used to specify a file extension for the generated files.

Although a default value of `eml` would be nice I have preserved backwards compatibility of no file extension by default.
