This PR should be good to review.

The Goal of this PR is to implement some base classes for RedM to allow players who want to use it to get started.

Some of these methods were taken from the original FiveM classes, notably the Model class. Though this shouldn't have any have any int -> uint (or vice-versa) calls.

This was also why the Game.GenerateHash native is unique for RedM & FiveM.

This change set also introduces a UiFeed class so the user can generate feed messages, if wanted these changes can be pulled out to leave just the base classes being implemented.
