Add link to Registration code (simple) -module to project page

I've written a simpler module for non-personalized codes: Registration codes (simple), https://www.drupal.org/project/regcode_simple

I propose an addition to project page which would suggest using that module for simpler use cases, where sent emails nor personalized codes are not needed. Module provides a single code for all users and validatity can be verified using just a fixed code, or - for example - user's email's domian -part (useful for intranet sites et al.).

Registration code (simple) -modules project page link to this module.
