Allow specifying a file extension from options override (HTML for instance, helpful to preview in the browser)

[ragunathjawahar]

I am unable to use a different extension for the approved file name. Right now, I see the verifyAndScrub function has a namer var namer = new ManualNamer(dirName, testName);.

I followed the call stack and couldn't spot a place where I can specify a different extension for my approved file. I am new to JS, please let me know if I'm missing something here.

any news on this? I also would like to have a file extension other than .txt.
