index.html (Getting Started) and Quick Start

Might have stepped on a couple of Matei's edits in Quick Start.

However please note that there doesn't seem to be an "addJar" method used in these code examples.

If "("local", "Simple App", "YOUR_SPARK_HOME",
      List("target/scala-2.10/simple-project_2.10-1.0.jar")"
is a SparkConf object then maybe we need to make that clearer and put that part of Matei's language back in.

We pass the SparkContext constructor a

 application. We also call sc.addJar to make sure that when our application is launched in cluster
 mode, the jar file containing it will be shipped automatically to worker nodes.
