Add nodegroup targeting to publish module

[UtahDave]

Please add nodegroup targeting to publish module.
The following command fails now:

$ sudo salt-call publish.publish qa test.ping '' nodegroup

Returns the following stacktrace:

2013-01-30 13:27:10,054 [salt.minion                                 ][CRITICAL] Traceback (most recent call last):
