version 4.2.0

move toStdFunction() to pibase.h
refactor PIParseHelper, now it much more abstract and useful
fix PIIODevice::createFromFullPath() when whitespaces at start or end are presence
PIStreamPacker add events for start and end packet receive
PIClientServer::ClientBase add virtual methods for start and end packet receive. also one can enable diagnostics with enableDiagnostics() method
PICout now call flush() on each end of output
