Chat Class: Chat room management with talks stored in files

This class can be used to implement multiple chat rooms that users can access and talk with everybody in the same rooms.

It uses files to store the dialog lines that are redistributed to every user in a same chat room.

It can create chat rooms with access to a limited number of users. It may also prevent that more than one user with the same IP accesses the same chat room.
