Add project actions in Audit events

As part of the Audit events, we need to log important project actions. This is to be recorded when something happens in the project:

• Project created
• Project deleted
• Project renamed
• Project moved
• Change project visibility
• Add member
• Remove member

Additional information to be recorded:

• Who did the action (user id)
• Timestamp
• IP address

This information is available instance wide, in a new tab in the administration panel, under 'Audit events'.
