Implement weapon sync

[zpl-zak]

Introduction

Weapon sync should cover the ability to use an inventory, shoot and reload weapons, and perform damage to the environment (implicit) and other players.

The following tasks need to be covered:

• aim sync
• inventory
• reloading
• shooting
• weapon switching

Scope

This issue covers both game research and network-related work.

[Segfaultd]

At the moment, we can detect aiming / shooting from the local player, broadcast over network, but we cannot apply it back on a remote ped on another networked instance.

Tried to use the sync data with scripted actions ScrAim and ScrAimAt but was instant crash.
