.expandAll() for Accordian plugin

[cdomigan]

Would be handy to have expandAll and closeAll functions that can be triggered.

$(".selector").activate(-1) will close all open menus...

If you wanted to expand all, there are several ways to do so, a) untested for ($x=0;$x<number_of_elements;$x++) {

$(".selector").activate($x);

} b) do them each one at a time by using the activate command

The point of the accordion is to *not* allow more then one part being open. Closeing everything is already possible.
