Title: VAT identification number for Poland

Added VAT IN (value added tax identification number) generator for Poland.
This is an identifier used in many EU countries (http://en.wikipedia.org/wiki/Value_added_tax_identification_number)
I'm not sure what is a equivalent number in other parts of world ;)

It's often situation (especially in a business oriented services) when you need to pass this number to a sign up form or just create company object with correct VAT IN.

With this pull request, it is easy to add generator for additional countries.
Just create class in lib/faker/vat dir, which respond to number method.
E.g.

```ruby
module Faker
class Vat
class Germany

def self.number
# generate correct number
end

end
end
end
```

and call it using:

```ruby
Faker::Vat.number :germany
```
