psychon 79212882e3 Fix a theoretical crash on shutdown ...

CZNC::~CZNC() set its pointer to the CConnectUserTimer to NULL and then called
the manager's Cleanup(). If some destructor that is called from here then calls
EnableConnectUser(), a new CConnectUserTimer is created and its address is
saved. But since the manager is destroying all timers, this pointer will soon
become dangling and might crash us later on.

This is solved by clearing CZNC's pointer in CConnectUserTimer's destructor.
