Subject: Changed system-ID of primary transformation to working directory *
 this change was needed so that one is able to apply transformations located
 in e.g. a central directory as if they where located in the working directory
 ** otherwise e.g. the BuildXSLT transformation would have to be copied into
 every project that requires it * implemented StreamInputSource wrapper for
 boost::filesystem::ifstream and xalan::XSLTInputSource ** this is needed
 because the boost::filesystem::ifstream instance has to exist as long as the
 xalan::XSLTInputSource it is bound to ** i.e. a simple helper function to
 instantiate the source and set the working directory would have not been
 sufficient
