ACL List doesn't support pageToken #321

I am trying to list the full ACL of a Calendar, but it gets truncated at 100 
items. I try passing the 'nextPageToken', but I get an exception: "TypeError: 
Got an unexpected keyword argument "pageToken". Passing "pageToken" in 
service.event().list() works, but it doesn't work for service.acl().list().

I believe this is a bug.
