Update README.md

[userlond]

I use jquery.modal version 0.8.0.
Why I've made changes in readme is in the code section below.

$('#container').on($.modal.BEFORE_OPEN, function(event, modal) {
    // prints undefined
    console.log(modal.$elm);    
    // without dollar sign it works
    console.log(modal.elm);
    // blocker works with dollar sign 
    console.log(modal.$blocker);
});

Maybe it will be ok to skip this request prior to some twiks in code to unify properties name (i.e. make working modal.$elm and modal.$blocker (or modal.elm and modal.blocker)).

Thanks for pointing this out — I actually stumbled across this exact issue myself today!

To fix without breaking backwards compatibility, I simply aliased modal.$elm and modal.elm — they will both work as of version 0.8.1.
