HTTPTestRunner update

[julien1]

I have updated the test runner so that it does not require to be subclassed to specify the file that will be deployed for the tests.

Before we had to have:

public class MyTest extends HTTPTestRunner
{
 public MyTest()
 {
 super("mytest.war");
 }
}

now we can use:

 <zest todir="${test.reports}"
 name="org.jboss.portal.test.framework.runner.HTTPTestRunner"
 outfile="TEST-MyTest"
 id="MyTest">
 <parameter name="archive" value="mytest.war"/>
 </zest>

the id will just be used by the XML report generator to identify the test name (until we write a test runner not based on JUnit ant tasks).
