Switched member initialization to std::make_unique

* i.e. InputXSLT now requires a C++14 supporting compiler / standard library implementation
* this was done while enabling the StreamInputSource to handle all kinds of streams
** this in turn is required to enable e.g. stdin as transformation source while preserving the correct filesystem context
