Use of config() instead of rw_config() in authlogic_openid 1.0.3 with authlogic >= 2.0.12

[vazqujav]

Authlogic-Changelog for 2.0.12 released 2009-5-13 reads:
Changed config() convenience method to rw_config() to be more descriptive and less vague.

...but methods 'required_fields' and 'optional_fields' in 'lib/authlogic_openid/acts_as_authentic.rb' still use config().

This results in a NoMethodError for people using authlogic-openid in combination with authlogic >= 2.0.12.
