Custom __deepcopy__ for LazyLoader

Browse Source 
When running JJB under py3 (py3.6) it started to fail with exception

  TypeError: cannot serialize '_io.BufferedReader' object

This is happens when doing deepcopy of a LazyLoader object which
contains an instance of BufferedReader object.
Under py2 this works but under py3 it is not.

This commit adds custom __deepcopy__ method to LazyLoader that
avoids deepcopy of a self._loader.
