Try this,

Tutsplus_Demo.xml

<?xml version="1.0"?>
<config>
  <modules>
    <Tutsplus_Demo>
      <active>true</active>
      <codePool>local</codePool>

    </Tutsplus_Demo>
  </modules>
</config>

}

<?php
class Tutsplus_Demo_IndexController extends Mage_Core_Controller_Front_Action{
    public function IndexAction() {

      $this->loadLayout();   
      $this->getLayout()->getBlock("head")->setTitle($this->__("Demo"));
            $breadcrumbs = $this->getLayout()->getBlock("breadcrumbs");
      $breadcrumbs->addCrumb("home", array(
                "label" => $this->__("Home Page"),
                "title" => $this->__("Home Page"),
                "link"  => Mage::getBaseUrl()
           ));

      $breadcrumbs->addCrumb("demo", array(
                "label" => $this->__("Demo"),
                "title" => $this->__("Demo")
           ));

      $this->renderLayout(); 

    }
}

Try this file along with directory naming structure.In your case its important to take care of it.

1) app\etc\modules\TutsPlus_Demo.xml

<?xml version="1.0" encoding="UTF-8" ?>
<config>
    <modules>
        <TutsPlus_Demo>
            <active>true</active>
            <codePool>local</codePool>
        </TutsPlus_Demo>
    </modules>
</config>

2) app\code\local\TutsPlus\Demo\etc\config.xml

<?xml version="1.0" encoding="UTF-8" ?>
<config>
    <frontend>
        <routers>
            <tutsplus_demo>
                <use>standard</use>
                <args>
                    <module>TutsPlus_Demo</module>
                    <frontName>demo</frontName>
                </args>
            </tutsplus_demo>
        </routers>
    </frontend>
</config>

3) app\code\local\TutsPlus\Demo\controllers\IndexController.php

class TutsPlus_Demo_IndexController extends Mage_Core_Controller_Front_Action
{
    public function sayHelloAction() {

        echo "Hello World!";
    }
}

Hope this will help you to identify you mistakes.

Following is the output which i get from above code.
