title: junit assertEquals ignore case
body: <p>im just moving from c# -> java. I need to write some tests using junit. 
  In my test i need to compare two strings to see if they match.
  So we also have the Assert.assertEquals, but this is case sensitive. How can i make it case insensitive?
  What i need is:</p>
  
  <pre><code>"blabla".equals("BlabLA")
  </code></pre>
  
  <p>to return true. </p>
  
  <p>So in C#, we used to have :</p>
  
  <pre><code>public static void AreEqual (
      string expected,
      string actual,
      bool ignoreCase,
      string message
  )
  </code></pre>
  
  <p>I was quickly going thru Junit docs, but i can't seem to find anything like this. </p>
