Activity page

Hi,
I added a feature that allows you to link directly to a service's activity from the /activities page by storing the key for the service. This has been useful for me to quickly delete a  bad activity, or just to view it.

You might even be able to start dedupe already synced activities based on the ServiceKey.

Let me know what you think.

Would a service ever have multiple ServiceKeys for the same activity?
