Keep the init visible state

[nflucian]

If the input is display:none, after applied this plugin it will be visible
Fix:
on setPlaceholder function get the init visibilit state

var visible = $input.is(':visible');

and at the end

// set up the init visibility state
            if(visible) {
                $input.show();
            }
            else {
                $input.hide();
            }

Just to clarify the @nflucian answer: add that code the the beginning and end of the setPlaceholder function inside jquery-placeholder.js. Works great for me!
