Title: @sporkmonger:  Added function-paramter to wrapping function in OAuth2-Client

@ sporkmonger (maintainer):
Wrapper refresh!() accepts same parameter as wrapped function fetch_access_token!().
For some services, it is necessary to send specific individual additional parameters when refreshing the access token, eg. Highrise expects the parameter "type" to be set to "refresh".
