Updated prefs to include SM upload settings.  Also updated SecShare peg.

1) That's how the URL is built out in the browser (I've tested and it works)
2) The null user name is handled in the upload method [here](https://github.com/scalio/SecureShareLib/blob/master/SecureShareUILibrary/src/io/scal/secureshareui/controller/ArchiveSiteController.java#L116)
