Bugfix: NullPointerException when calling render() on root node. Call will now be ignored as there's no place to write the data to however it makes to call it anyway, to handle different Templates uniformly. Call to render(String sibling) will still throw NPE as root has no sibling and thus the expected behavior can't be fulfilled. git-svn-id: https://svn.code.sf.net/p/snippetory/code/tags/snippetory-0.9.4.1@116 154fa62a-ae8f-480d-91fd-dc75d68c4636
