StackContainer/TabContainer: support non-fixed sized

[bill]

The doLayout flag from 0.4 days is broken, and needs to be fixed...

StackContainer? has a doLayout flag that you use to make the height of each pane equal. Example #1:

<div dojoType="dijit.layout.StackContainer" style="height: 300px;"
                doLayout=true>
   <div dojoType=...> short content </div>
   <div dojoType=...> long content </div>
</div>

When the above widget is displayed, regardless of which child is being shown, it will be 300px tall. There will be a scrollbar if necessary, or added whitepace to extend the short content to 300px.

Example #2:

<div dojoType="dijit.layout.StackContainer" doLayout=false>
   <div dojoType=...> short content </div>
   <div dojoType=...> long content </div>
</div>

When the above widget is displayed, it will change height depending on which child is being shown. All it basically does is show one div and hide the others.

As a bonus, maybe we could detect if the user wanted layout automatically, rather than needing a doLayout flag. Seems like we could detect if the user wanted us to adjust heights by whether or not height was set explicitly on the StackContainer? widget. The problem is that the height may be set explicitly, but indirectly, via CSS:

<style>
  #foo { height: 300px; }
</style>
<div dojoType="dijit.layout.StackContainer" id=foo >
   <div dojoType=...> short content </div>
   <div dojoType=...> long content </div>
</div>

see #4019

This should be fairly trivial (just don't call resize()) on the child, but the one trick is that the parent object should/shouldn't have the (confusingly named) isContainer flag if it is/isn't doing layout. See ContentPane for comparison.

I'll work on this for 1.1 if I have some free time for it; otherwise will defer to 1.2.

I know we don't have bugzilla style voting for bugs, so consider this my "+1" for getting this into 1.1

(In [13092]) Get basic TabContainer? doLayout=false working. Refs #3450. More complex cases probably aren't working yet and the CSS needs some tweaks too.

Move all milestone 1.1 tickets to 1.2, except for reopened tickets and tickets opened after 1.1RC1 was released.

This is sort of working already but not completely so leaving open for 1.2.

OK, this is working now (for tabs w/the tab labels on top, only).
