Add cache functionality

[marcofranssen]

Is it possible to add different caching strategies, so you can configure data to automatically expire and be removed from sterling db.

For example rolling cache, so data older than month auto expires and be removed. Make this configurable for all objects in the object tree.

Example: contact.Picture.Expires(new TimeSpan())

This will be very helpful when storing large amounts of data on budget devices.

Integrating this option in sterling could be much better for performance.

We don't have any current plans to add this to Sterling. We do, however, accept pull requests. :-)
