Silence QOL Fixes

SILENCE QOL FIXES Server-side quality-of-life, progression & GM power tools for Arma Reforger. >>> WORK IN PROGRESS - core systems are stable; the newest additions are still being play-tested. Status list at the bottom. <<< --- PLAYER PROGRESSION --- * Persistent XP & ranks: players keep XP across sessions and restarts, saved server-side. A per-server switch (PersistentXP_Enabled.txt) lets each server choose: XP carries over, or resets every restart for session-based ops. * Persistent combat stats: kills, deaths, team kills, suicides, captures, score and vehicle kills are stored separately and ALWAYS carry over - until an admin clears them via the GM "Reset Server Stats" action or by deleting the stats file. Independent of XP. * Extended ranks: progression continues past vanilla into three custom tiers - Veteran, Senior, Staff - with insignia on map, editor and nametags. * Starting XP floor (PersistentXP_StartingXP.txt): raise every joining player to a chosen XP so a season can start at a free rank. Never lowers anyone. * Promote / Demote from the right-click menu; a Staff Rank dropdown in a player's Edit Attributes jumps straight to a tier or strips it. * Season resets: wipe all XP (stats untouched) via a server file edit or a two-step in-game GM action (arm + confirm). * Stats overlay (F10): borderless readout of rank, XP, XP to next rank, kills, deaths, K/D, vehicle kills, captures, score and live global rank. Numpad 4/6/8/2 repositions, 5 resets. --- GAME MASTER TOOLS --- * Toggle Visibility - hide/reveal any AI, vehicle, player or prop. Hidden players vanish COMPLETELY: model, nametag, vanilla squad map markers, Player Map Markers, interaction prompts - and AI break off attacks on them. Network-safe for reconnects and late joins. GRS ATAK coverage via the Silence ARGC Patches - GRS companion. * GM Stealth (checkbox in a player's Edit Attributes): everything above PLUS hidden from other Game Masters' editors, exempt from Reveal All, and no player collision -...
