Fixed bugs in error handling in CTCPSocket; previously was not 

handling read errors at all and error handling for writes was
never being used.  Now the socket disconnects if a read or write
fails on the socket for any reason except EINTR.  Also added
<netinet/in.h> to includes in CNetwork.h because it's needed on
some platforms.
