Title: Fix for incorrect handling of requesting fields on an association. Currently (as of 5/22/2012) erroring out on Facebook.

If we request specific fields on an association, e.g.,
user.friends(:birthday, :first_name, :last_name)
the fields need to be translated into a single comma-separated parameter
for Facebook to respect it. Similar fix to c7b7fd8e
