Improve Password Initialization

Description

Currently the application (mifos) user password is encrypted using the UpdateMifosPassword class. This class is in test and requires running the ant target "update_mifos_password". The implementation of this class should be moved so an administrator can configure the application user password without requiring Ant.

Proposed Implementation

The password should be changed at application startup, possibly in init() implementation of servlet. OR another implementation.
