add replyto parameter :using a constructor or separate method

Done !

Should I do another pull request or you can see my commits ?
I did not really understood what you mean by "I'd also like to use proper camel casing that matches the API method setReplyTo on the parameters and setters/getters"

It'd be great if you could do it, its good practise :) I'd also like to use proper camel casing that matches the API method setReplyTo on the parameters and setters/getters. Easiest for you is to just add a commit, then squash them together into one (via rebase) and then force push on the according branches. Do you know how to do that or do you need help on that?
