Corrected the namealias jsdoc plugin to not include PIXI-from-YUI docs.
This is because they lack corresponding javascript code and need the
'name' property to remain intact.
Added support for short `{@link #member}` markup. This makes interlinking
much cleaner and shorter; similar short-link support was available in
previous versions of jsdoc.
The namealias plugin gets jsdoc to detect lots of documentation it was not
correctly picking up due to the application of the `name` property. This
can be read about in
https://github.com/jsdoc3/jsdoc/issues/804#event-195287680 - this results
in _much_ more complete documentation generation, especially when
properties are defined in constructors.
Added the filterpixi.js jsdoc plugin which marks some PIXI
interaction-related methods and properties as private. This ensures that
they do not show up in the final Phaser documentation.
