Added destructor code to avoid throwing exceptions while cleaning up any sockets. Destructors should not throw exceptions and socket handles should always be closed even if no connections were made.
Fixed SIGPIPE bug - transmit and receive functions in networking were using NOFLAGS instead of NO_SIGNALS. As a result broken pipes would raise SIGPIPE on *nix systems -- the coded did not expect that. NO_SIGNALS is not defined for win* systems so an ifdef was added to create NO_SIGNALS like NOFLAGS where it is not defined on win* systems. Win* has no concept of signals so this is a non-event for win* systems.
