#16 Changing password

[Plamen Tanov]

In user edit view should be added rendered="${empty password}" to:
<kqb:field fieldName="password" label="#{messages['entity.user.password']}" entity="#{teacher.data}" />
to disable hashing password twice.

To change password user should go to CHANGE_PASSWORD view...

As in first time creating password it should be retyped twice (not implemented yet)...
