Conflicts:
	App/App.pro

App/App.pro simplified by using ROOT's root-config to determine ROOT's
installation directory; environment variable $ROOTSYS no longer needed;
we only request that $ROOTSYS/bin is in $PATH (otherwise root-config
won't be found)

Directory pub/core contains
- symbolic link to .cpp and .h files in Core/*/src and Core/*/inc
- configure.ac, Makefile.am, and files generated by autoreconf -if
Try ./configure; make; make install
