Using define method instead of class eval when defining model callbacks.
Based on my benchmark results, this change improves performance
substantially when defining callbacks.
This benchmark (https://gist.github.com/wangjohn/5542610) was run using
the current master and also using my experimental branch which replaced
class_eval with define_single_method.
Using class_eval (current master):
