reworked settings menu

modular design to avoid code repetition, the basic information is kept in some category tables instead and run through a loop to populate the vgui elements

networking with the pac settings manager instead of PANEL:SetConVar (removing the need to create cvar copies) to avoid issues with the client-server realm fracture

menu gets a copy of each cvar's values from the server when opening, the changes are kept in memory, the menu has a prompt on close to ask whether to send the changes to the server

added the reveal outfits on +use cvar

new net message will send data to the client realm for the reworked settings.lua menu
