Add an on/off parameter to toggleClass()

[arrix]

Please consider adding an on/off parameter to jQuery.fn.toggleClass() so that we can write

$('#button-signIn').toggleClass('disabled', hasSignedIn);

instead of

$('#button-signIn')[hasSignedIn ? 'addClass' : 'removeClass']('disabled');

I think adding/removing a class according to some state is a frequent need.

I think this could be useful but at first it doesn't read very clear.

We don't plan on implementing this feature in core - feel free to create a plugin for it.
