Summary: Copy SQL statement in SQLQuery

Initial Comment:
This patch copies the contents of the stringstream

buffer (i.e. the SQL statement) in the SQLQuery copy

constructor and assigment operator.



This allows the following:



Query query = conn.create_Query();

query << first_sql_statement;

// ...

query = conn.create_Query();         // (1)

query << second_sql_statement;

// ...



currently the two statements would be run together

because the contents of the stringstream are not

cleared by the assigment on the line marked (1).



I've also explicitly initialised all members in the

constructors and  (arguably) improved my comment about

the std::ios virtual base class and calling init().
