System Logs to keep track of the events during an investigation

[kasunbalasooriya]

The logs can be used when generating reports and to prove the data integrity of an investigation. Add logs wherever possible and applicable.

eg:

• Assigning a new investigator to a case.
• Removing an investigator from a case.

We have the logging mechanism implemented in the system, however, currently very few actions are logged using it. We should implement this system wide.
