DOC: add a special acknowledgement for the stud project

Really, the quality of their code deserves it, it would have been much
harder to figure how to get all the things right at once without looking
there from time to time !

+ * Acknowledgement:
+ *   We'd like to specially thank the Stud project authors for a very clean
+ *   and well documented code which helped us understand how the OpenSSL API
+ *   ought to be used in non-blocking mode. This is one difficult part which
+ *   is not easy to get from the OpenSSL doc, and reading the Stud code made
+ *   it much more obvious than the examples in the OpenSSL package. Keep up
+ *   the good works, guys !
+ *
+ *   Stud is an extremely efficient and scalable SSL/TLS proxy which combines
+ *   particularly well with haproxy. For more info about this project, visit :
