Use of insecure component safer eval

Hi there,

I noticed that this project uses a component (safer eval) which suffers from a security vulnerability, you may want to check how the presence of this vulnerability impacts your users. I have written up an analysis of the bug here: http://justanotherhacker.com/archives/2016/04/29/analysis_of_the_safer_eval_code_injection_aka__the_wahckon_bug/index.html
