3 slot quickswitch, vm toggle, http://redd.it/2n7434

// This script allows settings to switch with the active weapon.
// Only the first 3 slots will be tracked by the scroll wheel and q, specifically this excludes the disguise kit (Spy) and the PDAs (Engineer).
// Medic, Spy, Engineer, and permanent non-active weapon versions are also available, contact the author below.

// The script will only work correctly when switching with keys in the BIND section.
// The script cannot know if a weapon switched for any other reason than player input using the keys in the BIND section.
// The script cannot know if a weapon switched successfully, and will always assume it has. Examples that prevent/impede switching:
//  - Permanent or temporary non-active weapon like gunboats or a melted spy-cicle
//  - Minigun spinup/spindown

// ========== INSTRUCTIONS ==========

// Edit r_drawviewmodel in the SETTINGS section for whether viewmodels are initially turned on (1) or off (0)

// To add additional settings on weapon switch, append them to the eq_ aliases.

// To change which keys can switch weapons, change or add lines in the BINDS section, binding keys only to the aliases already in the binds section
// Multiple keys can be bound to the same alias and the script will still work correctly

// See the following for information on how to install scripts and how to make them class-specific:
// http://www.reddit.com/r/tf2scripthelp/wiki/introduction

// To "undo" the script and changes made, remove the script from your relevant cfg files and execute the lines in the SCRIPT OVERWRITE section (remove the comment marks first)
