Proposal: separate loading of security files.

[Hans Bakker]

Problem:

Currently security files are loaded as part of seed. Therefore it is 
difficult to allow access to components differently per tenant.

Proposal:
1. create a new data-reader name 'security'.
2. Be able to load specific security files in a custom component and use 
in ofbiz-component.xml the component:// notation
3. now in the custom component can be defined which components should be 
active.

Any opinions or suggestions?

Hans
