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.

See below comment about the multiple of the same activity on the same service. Maybe too much for the feature but it did help me clean up some of my older activities that got synced too many times.
