Missing GsSocket exceptions about zinc HOT 2 CLOSED

I noticed this error, when the socket closes unexpectedly - then a SpSocketError is thrown.

ZnMultiThreadedServer>>writeResponseExceptionSet
"Returnt the set of exceptions which, when they occur while writing a response,
are interpreted as equivalent to a timeout or connection close."

^ self exceptionSet: #(#ConnectionClosed #ConnectionTimedOut #PrimitiveFailed #SpSocketError)

and

readRequestExceptionSet
"Return the set of exception which, when they occur while reading a request,
are interpreted as equivalent to a timeout or connection close."

^ self
    exceptionSet:
        #(#ConnectionClosed #ConnectionTimedOut #PrimitiveFailed #ZnParseError #ZnCharacterEncodingError #ZnUnknownScheme #ZnPortNotANumber #ZnTooManyDictionaryEntries #ZnEntityTooLarge #SpSocketError)

from zinc.

Added SpSocketError to read/write exception sets...will be available when issue_58 branch merged to master (Issue #58)
