Positioning the column. MySQL only

Add support for MySQL column positioning via #add_column and #change_column

add_column and change_column in the MySQL adapter now accept some additional options:

:first => true # Put the column in front of all the columns

:after => column_name # Put the column after ‘column_name’

class AddLastNameToUsers < ActiveRecord::Migration
  def self.up
    add_column :users, :last_name, :after => :first_name
  end

  def self.down
    remove_column :users, :last_name
  end
end

or

class AddIdToUsers < ActiveRecord::Migration
  def self.up
    add_column :urers, :id, :first => true
  end

  def self.down
    remove_column :users, :id
  end
end
