Show Deleted Activities in a Global Activity Log

[#1]

Description:
The current activity log works for Inactive, Active and Archived activities but there is no way to view a log for deleted activities. There should be a log for deleted activities.

Why is this feature important to you: 
For auditing purposes.

Current Behaviour:
Currently the activity log is localized to each individual activity and there is no global activity log. This means if someone deletes and activity there is no record of who deleted it and when. 

How would you like the feature to work: 
It would be ideal to have a global activity log that captures when an activity is deleted and by who.

It would be even better if we had a global change log, i.e. a cross-activity change log

Right now change logs are buried in each activity. If you are trying to find a root cause of an active error, you might know the incident start time, but not the activity causing it. We need to dig through each activity. Ideally in the admin tab, there would be universal change log that could be narrowed down by a time range. This should not be API driven, as we might be in an all-hand situation, like turning on redirect sitewide. 

Deleted activity logs could live within this interface. An additional filter could be added based on change type (activation, deletations, updates, etc.
