Bug fixes and usability improvements (+ IIS support)

Hi Anant Garg,
It's been 3 years or so since you last updated the Qwench repo: 

1. Are you still developing this product? 
2. If so are you interested in pull requests?

If you are, please find enclosed bug fixes and usability improvements that will not change existing functionality.

It also includes IIS support through a web.config file.

I noticed that the moderator side of things doesn't exist, so I'm writing my own based on our requirements,  however if you appreciate pull requests for general code for this then feel free to let me know.

Kind regards,
Sander
