Remove docs and redirect to new website

With the new page in place, any visitors to http://demo.virtual.wf or http://development.virtual.wf will get redirected to https://virtual.wf. Yay!

As a side effect, if you start a VWF server locally with the full repo downloaded and go to http://localhost:3000, you'll also get sent to https://virtual.wf. Awkward?

This only affects developers who grab the github repo directly. Our installers omit the public directory altogether.

Thoughts?

@eric79 Could you review this?
