[SMSS]

- In the token parsing function SmpParseToken, just return success directly if the input string has zero length, instead of running code which does nothing at the end, because the length was zero...
- Give a default value for the "BootExecute" entry in the SMSS registry configuration table (this value is used when there is no BootExecute registry value inside HKLM\System\CurrentControlSet\Control\Session Manager) and precise that it is a multi-string value.
- Remove a redundant "Environment" entry in this table, too.
