slideDown()

[cweiske]

After sliding up and hiding the row, I'd like to be able to re-show the rows (restore a deleted row) in a slideDown-manner.

I think that makes sense, if the element is not being removed anymore via #1 then there should be a way to restore it.

In that case it might make sense to rename the methods rowslideUp and rowslideDown. It might even make sense to to overload the built in slideUp and slideDown methods to defer to rowslide equivielent if the element in question is a <row> element.
