VS Code API

Thenable is a common denominator between ES6 promises, Q, jquery.Deferred, WinJS.Promise, and others. This API makes no assumption about what promise library is being used which enables reusing existing code without migrating to a specific promise implementation. Still, we recommend the use of native promises which are available in this editor.
