moved files to the runtime

there are still some files left which could go into the
runtime, but I think we will delete most of them once we
are done with the full modularization.

+/* Definition of the generic obj class module.
+ *
+ * This module relies heavily on preprocessor macros in order to
+ * provide fast execution time AND ease of use.
+ *
+ * Each object that uses this base class MUST provide a constructor with
+ * the following interface:
+ *
+ * Destruct(pThis);
+ *
+ * A constructor is not necessary (except for some features, e.g. de-serialization).
+ * If it is provided, it is a three-part constructor (to handle all cases with a
+ * generic interface):
+ *
+ * Construct(&pThis);
+ * SetProperty(pThis, property_t *);
+ * ConstructFinalize(pThis);
+ *
+ * SetProperty() and ConstructFinalize() may also be called on an object
+ * instance which has been Construct()'ed outside of this module.
+ *
+ * pThis always references to a pointer of the object.
