dialog fadein broken since 1.9m4

[chadw]

$.effects.effect.fade changed between 1.9m4 and 1.9m5. Since then, I am unable to get a dialog to fade in (fade out works). Perhaps a CSS tweak didn't make it to the dialog widget? The .show() is suspicious otherwise.

Changing jquery.effects.fade.js:

	el.show();
	el.animate({ 
		opacity: hide ? 0 : 1

To this:

//	el.show();
	el.animate({ 
		opacity: hide ? 'hide' : 'show'

Fixes it.

Fade changed in 1eada2154910102e4c39d131a23af24ad0d92815 with no description of what the problem actually was, but looking at the test failure from the previous commit should provide enough insight.

Effects (fade): Delegate hiding and showing to core. Fixes #8267 - dialog fadein broken since 1.9m4.
