delete some api and refactor implement

1. only support `Class.create(properties)`, `Class(func)` instead of
`Class.create(func)`.

2. delete `Extends`, `Implements` properties, use `subClass.extend()`,
`subClass.implement()` instead.

3. delete `StaticsWhiteList`, I don't know why it exists.

4. delete `Statics`, use `subClass.prop` instead, supporting inherit
also.
