JUnit 3 test can be JUnit 4

Reports JUnit 3 test classes that can be converted to JUnit 4 test classes.

Example:

public class MainTestCase extends junit.framework.TestCase {
  public void test() {
    Assert.assertTrue(true);
  }
}

After the quick-fix is applied:

public class MainTestCase {
  @org.junit.Test
  public void test() {
    Assert.assertTrue(true);
  }
}

This inspection only reports if the language level of the project or module is 5 or higher, and JUnit 4 is available on the classpath.
