Added Seed Data for the App

I changed the seeds.rb file so that it reads the charities date from the data.csv file and creates the records in the organizations table. After we add authentication to the site, i think we can then migrate this data. You can set the no. of records that you want to create in the num variable in the db/seeds.rb and then run rake db:seed and voila. But you can add upto 1006 records which is the number of charities I have in the data.csv file.

Also updated Rails to 3.2.13
