slideIn()/slideOut don't work for aborted operations

[bill]

Basically, the code that I added to wipeIn/wipeOut, which Alex ported to dojo 0.9, to handle nodes with fixed height setting (like node.style.height="300px") is doing more harm than good. Specifically it messes up when (for example) you halfway open a title pane and then abort and start to close it.

So I'd like to just support natural height divs. If you want a fixed height div, just do something like:

<div>
   <div style="height: 300px">...</div>
</div>

The contract for the functions will be:

1. slideIn() (like fadeIn()) will expand the node from it's current height to it's full natural height
2. if the node is display:none then before the animation starts it will set it to height:1px, display:""
3. slideOut() (like fadeOut()) will collapse the node from it's current height to 0 height, and then make the node display:none (and height:auto)
4. play()'s signature is: play: function(/*int?*/ delay, /*boolean?*/ gotoStart). If you set gotoStart to true then the height will be set to 0 (for slideIn()) or auto (for slideOut()) before the animation starts.

changes seem fine

I hope my suggestion above works... I'm worried about how to deal w/the width of the title pane. Needs some testing/thinking.

(In [9498]) Make slideIn()/slideOut() assume a natural height for the node, rather than trying to obey a height specification on the node's style. This simplification fixes #2944, #2343, #3152
