Force tokens during install and begin to force tokenization

I have also added an install hook and update hook only in the 4.x branch.

Install hook will preset the 2 tokens for orchestrator and sitewide token. It is suggested that you configure those for your own purposes. They are mandatory.

The update hook will update any open task with a token (If it doesn't already have one). If you are manually tracing and changing status of closed processes or tasks, you are responsible for setting tokens on those tasks which are now unarchived and not completed.

Notifications to be updated next.

Default notifications now use token instead of queueID.
