GFilterOutputStream, from which CamelFilterOutputStream is derived, defaults to closing its base stream when the instance is finalized. That makes sense in the general case, but CamelFilterOutputStreams are usually temporary wrappers on a more permanent base stream, so we need to remember to override the default "close-base-stream" property value. I was tempted to just make CamelFilterOutputStream override the default automatically, but I decided against it because my long term plan is to drop CamelFilterOutputStream for GConverterOutputStream which also does not override the "close-base-stream" default. The closer the semantics of the two classes match, the easier porting will be in the future.
