Add extra validation rules to Laravel ForgotPassword

ES6 support on iOS9
Recently while building a Cordova based app, few users complained that they were seeing blank pages or cryptic error messages. Someone mentioned they were on iOS9.

Jenkins parallel pipeline
I was very excited to know about the ‘parallel’ feature in Jenkins Pipeline, but, there are many gotchas while making use of the pipeline feature (many of which are documented here: Jenkins Pipeline Example).
