Fix export, which has been broken since the boost::signals2 changes. Also update Audiographer, bacause of its incomplete sndfile handling. Audiographer is equal to revision 74

+AudioGrapher is Copyright Sakari Bergen 2009-2010
+
+AudioGrapher is best described as a signal flow management library.
+It includes facilities to build graphs out of signal processing elements.
+Once a graph is set up, all signal flow within the graph happens automatically.
+
+The data flow model in Audiographer is dynamic instead of synchronous - the type
+and amount of data that goes in to a graph may differ from what comes out.
+AudioGrapher is aimed mostly for usage by developers, as it includes lots of
+facilities that ease the development process.
+
+The main aim of AudioGrapher is to ease development and debugging of signal flow
+graphs. It makes heavy use of modern C++ techniques like templates, and uses the
+boost libraries a lot.
+
+The essential classes in AudioGrapher are Sink, Source and ProcessContext. These
+three define the signal flow in a graph. In addition, the core of AudioGrapher
+includes lots of utility classes.
+
+AudioGrapher includes a bunch of ready Sink, Source and Vertex implementations.
+Some are utilities used when developing more vertices, while others are general
+utilities (file i/o, sample rate conversion etc).
