Benefits from Typescript

Wechaty is fully typed by TypeScript since v0.5, 12th Oct 2016. And got benefits as the following:

1. Better async coding style: async/await (now we use co module)
2. Strong type definition/checking for data structure
3. Auto-completion/Static syntax check with VSCode IDE
4. Static variable that can initialize inside class
5. Public/private setting for methods/member variables
6. other benefits...

The lastest javascript version is: v0.4.0(2016/10/9)

VSCode is highly recommended as developing IDE for Wechaty with TypeScript because we can get the benefit of intelligent code completion, parameter info, and member lists.
