Remove dummier and checkin dummy app
Fix specs

Remove validations on taxid and manager_contact - should be up to app to
add those if desired (not in my use case)

Add development dependency on github version of spree_auth_devise, since
published gem does not have needed admin_users_path
All tests passing

Added placeholder WholesalerMailer, but does not have text of emails.
Should also use the name of the configured site from Spree.
