missing class "pq-focus-mgr" on the textarea

[jplevene]

The focus textarea no longer has the class "pq-focus-mgr", so when I detect a body keypress, the target is a textarea with no class to distinguish what it is.

In 9.0.2, only the parent div has the class "pq-focus-mgr" and not the textarea like before.

Sorry the classes which are used internally by grid and not specified in the API documentation can be changed anytime.
