TabPane firing show/hide several times during selection action

[Tom Trenka]

If you try to attach an event to a Tab widget, like so:

var tab=someTabWidget; dojo.event.connect(tab, "show", myObj, "myHandler");

it looks like show is fired on widget render, on widget resize (my fault, I know), and on *any* tab widget select, even if the tab selected is not the tab the event is attached to.

It would seem like good idea to either fire tab.show() only when that actual tab is shown, or provide a place for people to attach event handlers for when the tab is actually selected, either via UI event or programmatically.

Should be fixed after #3180.
