message: fix changelog having wrong changes for Curl.code
diff: @@ -26,9 +26,9 @@ and this project adheres to [Semantic Versioning](http://semver.org/spec/v2.0.0.
  - `Curl.reset` now correctly resets their instance ([#141](https://github.com/JCMais/node-libcurl/pull/141))
  - Previously `Curl.code` had all Curl codes into a single enum like object, that is, it included properties for each `CURLMCode`, `CURLcode` and `CURLSHcode` libcurl enums.
  Now they are separated, each on their own object:
  - `CURLMCode -> Multi.code`
  - `CURLcode` -> `Curl.code`
  - `CURLSHCode` -> `Share.code`
  + `CURLMCode` -> `CurlMultiCode`
  + `CURLcode` -> `CurlCode`
  + `CURLSHCode` -> `CurlShareCode`
  - `DEBUGFUNCTION` now receives a `Buffer` as the `data` argument, instead of a `string`.
  - `Easy.send` and `Easy.recv` now return an object, `{ code: CurlCode, bytesSent: number }` and `{ code: CurlCode, bytesReceived: number }` respectively.
  - `Curl` class: removed `_` prefix from their private members.
