Changes in this version:
- Added command line support for exporting emails, attachments or properties. See the readme for a full description. Thanks to @stephenjannin for the initial work on this.
- For the convenience of developers building on this project, separated out the base Outlook file handling from the UI as XstReader.Base. This can be incorporated in your project either by referencing a DLL, or including the source code into your own compilation. Thanks to @iluvadev for the initial work on this and subsequent reviews.
