small fix due to version change
pulled forked changes in
If no last address is found in the user's order history, use the *user's*
billing address (current_user.bill_address) if it is available.
We should take a cue from the before_address method that we are
overriding in Spree core (core/app/controllers/checkout_controller.rb:69)
and use Address.default
Updated the Readme with the fact that it uses the customer's saved address, if any
Made compatible with current Spree version (1.3)

Updated gemspec and bumped version to 0.1.1

Added Versionfile

Also changed it to give priority to their preferred_bill_address (current_user.bill_address), *if
available*.
