Title: linkedin scope option

Linkedin supports the scope when requesting the token (e.g. permissions to get email address)

https://developer.linkedin.com/documents/authentication#granting

Passing the scope via URL did not work.
It seems the scope should be passed as an argument to getRequestToken()

I've implemented it on the linkedin class.
If some other oauth1 providers need a similar option, this logic can be moved to the parent class.
