fix #626 pageEngine `pageReady` event not fired in Chrome

CSS transitions are not performed in Chrome and in IE10 when the container
has `display:none`. Hence if `animationOut` was defined in animations
configuration, page engine's `pageReady` event was never fired.

Close #628.
doc remove jsdoc @name when unnecessary

@name is only needed if case when we want to document variables under
different names, or to document variables that are initialized outside
`$constructor` in `Aria.classDefinition`.

We have an issue with APIDoc extractor/viewer, it marks all props with
`@name` as `static`. By the time that gets fixed, this commit removes the
wrong `static` marker from some props. We still have `@name` though in
some other places (mainly modifiers and Aria singleton).

Close #631.
