Updated the Escort class

- Registering each excort at the client internally.
- Each escort known at the client can exchange targets.
- Each escort can acquire attack assistance from other escorts known at
the client.
- Made the MENU class more slick. Now menus are removed recursively for
CLIENTS.
- Added a few more types and fine tuned the documentation.
