FileSystemLoader's use of lambdas for uptodate callbacks is causing loaded templates to be unpickleable.

AttributeError: Can't pickle local object 'FileSystemLoader.get_source.<locals>.<lambda>'

We can solve this using a simple function and functools.partial, instead of a lambda function.

          Test async uptodate is pickleable too. See #107.
