jQuery replaceText - textarea support (?)

replacetext-textarea.js

// If you want jQuery replaceText to be able to replace modified content
// inside a textarea, you might need to do this kind of thing, since
// changing the textarea .value doesn't change the textarea's child text
// node!

$('textarea')
  .each(function(){
    $(this).html( this.value ).val( this.value );
  })
  
  .replaceText( /\btext\b/gi, 'TEXT' )
  
  .each(function(){
    $(this).html( this.innerHTML ).val( this.innerHTML );
  });

transform this into a pull request to the library but make the functionality optional as by default most people would not want to touch textarea contents.
