Create pokemon script

@thiagogabriel please take a look, I tested this script with the hubot from github, I got some errors when trying run our fork.
Just a little :scissors:. You can use the triple double quotes syntax to avoid these "\n".

```coffee
show: ->
  """
  #{@sprite}
  Name: #{@name}
  Type: #{@types}
  Description: #{@description}
  Height: #{@height}
  Weight: #{@weight}
  Attack: #{@attack}
  Defense: #{@defense}
  """
```
