IEs older than 7 had WebBrowser control implemented in shdocvw.dll. We 
surely don't want to run tests on anything older than IE6. IE6 results 
very little value in this case, so I consider DLL presence check as a 
nice way of skipping tests on too old platforms and I've even stripped 
the code from no longer needed checks that you want to add when I was 
moving them from shdocvw to ieframe, In this case, skipping tests is 
really a job for testbot.
