Invocation: able to build and invoke a simple Render Node (see: #1367)

Browse source 
**This is a Milestone for the Render Engine integration effort**

After various rounds of prototyping and refactoring,
the Render Node builder and invocation code is now able to
 * bind a simple function
 * handle arbitrary input / output and parameter types
 * invoke a Render Node configured with this function

Ich hatte schon angefangen, &#252;ber der m&#246;gilchen Implementierung zu &#187;br&#252;ten&#171; und mich wieder in BufferProvider + OutputSlot eingelesen. Erst nach etwa einer Stunde ist mir aufgefallen, da&#223; OutputSlot ja eine DataSink erzeugt, und da&#223; diese bereits eine <font face="Monospaced" color="#572d2d">lockBufferFor(FrameID)</font>-Funktion hat, die ein (TADAA!) BuffHandle liefert. Nicht wirklich &#252;berraschend, da ich ja beide Protokolle (Buffer Provider und Output Slot) kurze Zeit nacheinander entworfen habe. Daher konnte ich wohl damals auch einen Proof-of-Concept-Test ziemlich einfach &#8222;aus dem &#196;rmel sch&#252;tteln&#8220;...
