A brand new way to handle API methods for the version 2

- The `go` function is now easier to use and really handles a lot of things for you, including the creation of the URL
- The README explains in a better way how to implement API methods, for the other developers
- ALL the methods for the first version have been commented, in order to remake them for version 2 using the new `go` function
- 4 functions have made to start the version 2: get achievements, get one achievement, get users, get one user
- The `example` file is ready to make the unit tests for the version 2

Apologize for the big commit ^^'
