Improving Internal Effects API - Part 3

We could potentially leverage

 $.effects.$ = jQuery.sub() 

and extend its

fn

to serve up the setMode, save, restore, createWrapper, removeWrapper, and a few other helper functions that all take

 el 

as a first parameter. Each of the effect functions can then use

 $.effects.$( this ) 

and have all the helper functions available in a nice chain.

Got most of these changes in and you can look at the branch here: https://github.com/gnarf37/jquery-ui/compare/master...effects-sub
