[up-keep]elements are involved.
up.reveal()no longer crashes when called with a CSS selector or non-jQuery element.
up.reveal()now returns a rejected promise when no viewport could be found for the given element.
[up-expand]now ignores clicks on form fields. This is useful e.g. when
up-expanding a table row that contains both links and form fields.
a[up-preload]will no longer preload a link when the user holds the Shift, Ctrl or Meta key while hovering.
