Added a package level variable "InterfaceMarshalFunc".
It's used to marshal interface to JSON encoded byte slice,
mostly when event.Interface("key", v) is called.

// JSONMarshalFunc is used to marshal interface to JSON encoded byte slice.

// some extra efforts at importing, but avoids value copy when the functions

// DO REMEMBER to set this variable at importing, or

// you might get a nil pointer dereference panic at runtime.
