.fadeIn() + .fadeOut() + .fadeToggle()
Fixed HTMLElement#show() and IE NodeCollection error at the same time (iframe is now always persisted).
Also added a function that simplifies determining if an element's display style is "none" and also improves compression.
Added .slide*() functions and fixed the following:
+ .css() - Now has the same abilities as jQuery
+ .hide()
+ .show()
+ .toggle()
+ .fade*()
+ .animate()
