The template is not automatically registered under any name when passed to the callback, so the `onLoad` function should handle registration as it needs. `dust.cache` behavior has been changed slightly. Before, setting it to false would blow away the entire cache on every render. Now, setting it to false just prevents new templates from being added and cached templates from being used, but if it's set to true again previously-cached templates will be ready to use.
