Fix for #157

[orbanbotond]

The pg array type is now detected.

This is how the annotation will look like:

# == Schema Information
#
# Table name: equipment
#
#  id                 :integer          not null, primary key
#  shop               :string(255)
#  name               :string(255)
#  category           :string(255)
#  link               :string(255)
#  image              :string(255)
#  product_key        :string(255)
#  brand              :string(255)
#  created_at         :datetime
#  updated_at         :datetime
#  equipment          :string(255)
#  gender             :string(255)
#  sport              :string(255)      is an Array
#  asin               :string(255)
#  user_id            :integer
#  rotation           :boolean          default(FALSE)
#  colors             :string(255)      is an Array
#  sizes              :string(255)      is an Array
#  amazon_checked_at  :datetime
#  models             :string(255)      is an Array
#  year               :string(255)
#  product_attributes :string(255)      is an Array
#  color              :string(255)      is an Array

Do you mind rebase yours against the latest of the "dev" branch? Another minor suggestion is to replace "is an Array" with just "array".

Thanks.
