Added Wizard install feature

I've created implementation for ticket number #28008
usage is `brew install {formula} --wizard`

This pull request is meant to do two things, code-review, as I'm not Ruby programmer, and I probably messed up horribly, and testing.

Also if anyone would know how to pass the `--wizard` option correctly into `DependencyInstaller` instance, I'd be grateful, because that is the only thing I'm missing, to configure dependencies on-the-fly

work-flow and interface looks like this:
```
$ brew install avidemux --wizard
