task/us101-ta55 (commit 2) -- ADP column value to agent table SQL
sanitiser and validator

nparcel/conf/nparceld.conf
nparcel/b2cconfig.py
* new attribute delivery_partners which is a list of
  "delivery_partner.name" column values
* new attribute adp_default_passwords delivery partner lookup for the
  default password to use when populating the "login_account.password"
  field
* refactor the [adp_headers] section so that it includes the table
  name as we are now inserting into multiple tables and need this
  level of separation to avoid ambiguous column names

nparcel/adp.py
* support for new attribute delivery_partners
* new method reset() that clears the alert list and commits to the
  database as per the context of the pass
* refactor the sanitise() method to determine the delivery partner id
  before inserting to the agent table
* refactor the validate method to validate against the
  delivery_partner.id column
