FolderScanType of smb is assumed, support for FolderScanType of ftp (and associated parameters) should be supported

Found the module and gave it a whirl. Used it to update a bunch of address book entries, but then they stopped working. It looks as though there are some issues here:

1. FolderScanType of smb is hardcoded rather than accepting that parameter or respecting existing entries in the *-AddressBookEntry functions, so adding or updating entries causes any FTP entries to be changed to the smb type.
2. An entry retrieved from Get-AddressBookEntry cannot be changed and then piped into Update-AddressBookEntry because the object contains several properties (such as FolderScanType) that are not properly supported (even though they should be). Suggest adding support to accept the same objects retrieved from Get-AddressBookEntry into pipeline for Update-AddressBookEntry
