#define PLUGIN "Glow Menu"
#define VERSION "1.1"
#define AUTHOR "Demon RR"
#define MAX_COLORS 100
//This plugin allows glowing capablities for all players through the use of a menu.
//All colors for glowing must be in the file "configs/Glowcolors.txt" in the form of
//					Color	RED	GREEN	BLUE
//where Color is the name of the color to appear in the menu
//and RED GREEN BLUE are RGB values between 0 and 255
//each must be on its own seperate line and there should be no empty lines in between colors or at the end of the file
//by default 100 is the maximum amount of colors allowed in. That can be change by changing MAX_COLORS to a different value
//Changelog
//1.1
//changed so file now uses get_configsdir
//added amx_reloadglow to reload the Glowcolors.txt instead of restarting the server
//uses isalnum to for the file reader instead of the ascii characters (doesnt affect anything at all, just less code)
