- The inactivity flag is now also displayed in list users
- Fixed the time.h detection (especially Debian users
  suffered from this oversight)
- Channel admins can no longer add the "a" flag to other
  users making them channel admins
- List channels will now also list user count
- Added edit usermode, edit user and edit vhost
- All edit commands should now send a response
- Unified a bit the logic how responses are sent on add,
  edit, del and list commands
