Tab select/deselect methods should pass reference to tab

[viveleroi]

Currently, the tabset directive allows us to define select/deselect callbacks select="tabChange(). However, there's nothing on the scope that can be easily passed as an argument which references the tab.

What I'd like to see is something along the lines of:

select="tabChange($tab)"

Where $tab is the tab object with active, heading, and other properties. This is especially useful for those not using an ng-repeat to generate tabs.

Closing in favor of #4836 - keep an eye on that issue

I don't know if there is a better way, but this worked for me:

....deselect="func($event, $selectedIndex, this)">

And the javascript:

....function($event, $selectedIndex, caller) {
  caller.$parent.tabset.active = $selectedIndex;
}

You can get a reference to the tabset, not the tab. But you can look at active to find the tab, and $selectedIndex to find the new tab.
