Finalize acecool_weapon_base

Finalize all features, hooking system to make the system fully customizable via hooks ( meaning those that use default bullet system can leave as is vs using my theoretical bullet system vs those using default ammo system vs those using my magazine and bullet-type system... etc...

With all of the hooks that I'll be adding, every single element of the swep base will be customizable including allowing ClientsideModels as attachments, 2D/3D menus, etc...
