added: TextStream<> DbTextStream<> and HtmlTextStream<> have operator<<(Space&) now

added: to db: bool DbBase::AssertValueSpace(PGresult * r, int row, int col, Space & space, bool split_single)
added: environment variables for users
       User::env (of type Space) and
       User::aenv (of type Space) for admin variables (can be changed only by a super user)
added: winix function 'env'
       for changing User::env and User::aenv ('env' winix function with a 'a' parameter)
