Title: prompt for confirmation on destroy

Accepts confirmation via pipe to stdin, or prompts the user to confirm.

```
$ hk destroy myapp
warning: This will destroy myapp and its add-ons. Please type "myapp" to continue:
Destroyed myapp.

$ echo myapp | hk destroy myapp
Destroyed myapp.
```

Fixes #90.
