During asset conversion we noticed that the ColladaConverter does not produce binary-equal files with the same input file.
This caused problem's for us because our Source Control System (Perforce) always noted a change within the file and wanted to update the file.

The reason: SceneNode's and MorphTarget's "name" (char name[256]) not completely zeroed.

The attached patch zeroes-out the "name" member using memset in the respective c'tors (which seemed cleaner to me than doing this during the strcpy), so the same input file always results in identical output files (including animation).

Thanks Alex, this is indeed very useful, also for QA'ing ColladaConv (regression testing after refactorings).
