Create a Poll taskable type

I'd like for someone to have a look at this poll request. Get it? Poll … request? Because … this is adding polls? And a pull request for polls is a poll request? Eh? EH!?
Not sure I follow, but do you mean replacing it with something like this:

```ruby
resources :polls, only: [] do
  scope module: :polls do
    post 'answers#create'
  end
end
```
