Enhancement: setHoverDelay() for ListGridField

Hi Isomorphic,

4.1p's ListGrid inherits setHoverDelay() from Canvas.
Unfortunately there is no separate setter for ListGridField (if I want different delays on a per-field basis), as this does not inherit from Canvas.

Could you add such method (to 9.1p), as ListGridField already has a setHoverCustomizer?

Thank you & Best regards,
