Status update

Finished edits to an integral piece of the project - http-screenshot.

We were having a couple of problems w/ http-screenshot, but the showstopper in any large enumeration engagement is when the process freezes. It looks like wkhtmltoimage is hanging on scripted prompts, so i edited the .nse to have its own little timeout. I also rounded up all the changes proposed in Ryan Linn's original post and a little flow/optimization of my own.

Been using the updated ver for almost a week.... it works like a champ!

Updated ver can be found here - http://canhazcode.com/content/http-screenshot.nse. HTH!
