Title: Fix for authentication errors when additional params are in the parameters hash.

Use only the post parameters when calculating the signature for a request from Mandrill. Fix inspiration comes from issue on original repo (https://github.com/evendis/mandrill-rails/issues/11).

This fixes invalid signatures being calculated when additional params that rails adds are in the params hash (like controller, action, subdomain).
