Listing plugins on master is currently broken

[Kay Hayen]

Hello,

this is on master without changes:

../nikola/scripts/nikola install_plugin -l
[2014-04-13T21:07:53Z] WARNING: Nikola: Could not guess locale for
language en, using locale C

Traceback (most recent call last):

mod_path = sys.modules[self.__class__.__module__].__file__
AttributeError: 'module' object has no attribute '__file__'

Looking at it more closely, it attempts to resolve "__builtins__"
because of "CommandImportWordpress"
instance. This seems to be a regression I figure.

Yours,
Kay
