Remove const enum from default template

[alievrenkut]

Hi,

I really liked your library but I have an issue with a React project. Create React App project does not support "const enums" because of Babel. You can look at link for more information: facebook/create-react-app#5681

Could you remove "const" modifier from "enum" at client.mustache?

P.S: I know that in a ideal world I should create an issue at Create React App project but it looks like they will or can not fix it. So I create here.
