[Mysqlcppapi-main] Simplifying Connection

[Jonathan W. <co...@co...>]

In addition to removing the 2-stage construction (see other thread) I'd
like to further simplify the Connection by using the initialisation list
in the default constructor:

   Connection::Connection()
   : m_bLocked(new bool(false)), m_bSuccess(new bool(false))
   // etc. etc.
   { }

The copy ctor and assignment operator should be OK using the
compiler-generated one, rather than explicitly defining it, as all
members are builtins or types with correct destructors.

All comments welcome, especially if I've missed some reason this won't
work!
