Add support for documenting class properties

Adding support for documenting those would greatly improve my workflow, as I would't have to explicitly use getters and setters for each class property. Also, the @property JSDoc tag before a class declaration doesn't behave as expected for my use case.

Can these be documented using @memberof Class, and @static or @instance, the normal tags for static and instance properties?

[kripod]

That did work, thanks for the heads-up! Although, it'd be great if I didn't have to use those 2 extra tags.

export default class ModelBase {
  /**
   * Plugins to be used for the current ORM instance.
   * @type {Object[]}
   * @memberof ModelBase
   * @static
   */
  static plugins = [];
}

For those who are curious, my actual implementation mentioned above can be found here.

If you leave out @memberof ModelBase, is it inferred from the context? It should be, but I'm not sure of the status of documentation.js support for ES6 class inference.

[kripod]

No, the context is not detected correctly: in the example above, plugin gets treated as if it was hierarchically on the same level as ModelBase.

🍏 This works in current documentation.js 5.x

In:

/**
 * This is the model base.
 */
export default class ModelBase {
  /**
   * Plugins to be used for the current ORM instance.
   * @type {Object[]}
   * @memberof ModelBase
   * @static
   */
  static plugins = [];
}

Out:

### Table of Contents

-   [ModelBase](#modelbase)
    -   [plugins](#plugins)

## ModelBase

This is the model base.

### plugins

Plugins to be used for the current ORM instance.
