proposal.go

/*Explanation:
This code defines the User, Moderator, and Proposal structs, as well as the Moderators slice.
The User struct represents a user in the Forum application, and has fields for the user's name, message, and
whether they are banned.
The Moderator struct represents a moderator in the Forum application, and has a field for the moderator's name.
The Moderators slice holds the list of moderators in the Forum application.
The Proposal struct represents a proposal in the Forum application, and has fields for the proposer,
the proposed action, the user affected by the action, and a boolean flag indicating whether the proposal has been
approved by the validators.
The NewProposal function creates a new Proposal object with the given user and action.
The PrepareProposal method prepares the proposal for voting by setting the Vote flag to false.
The ProcessProposal method processes the proposal and executes the necessary action if the proposal has been approved. If the action is to add a user, the method sets the IsBanned field of the user to false. If the action is to delete a user, the method sets the IsBanned field of the user to true. If the action is to add a moderator, the method appends the moderator's name to the Moderators slice. If the action is to ban a user, the method checks if the user's message contains a curse word and sets the IsBanned field to true if it does.
