<p>This test attempts to change the src of an IMG tag to all black listed ports to confirm that WebKit returns the
correct error for them - blocked instead of cannot find.  It also tries the FTP ports for exemptions.  Due to the 
nature of this test, the results can only be processed automatically via DumpRenderTree
