[Proposal] Change auth_type in login url

[ChristianGrech]

I have been dealing with permissions being edited by the users and according to the documentation you need to append auth_type=rerequest to the url.

I was looking for a way of doing it using the api however, I could not find out how, so I am currently doing it manually.

It would be ideal to add a parameter in the FacebookRedirectLoginHelper->getLoginUrl() method which will let you to specify the auth_type.

A parameter has been added to FacebookRedirectLoginHelper->getLoginUrl() which appends auth_type = rerequest to the URL. You can see it here: rajbdilip@a0508f4
