In cvar_change, you can actually replace this type of check:

	if (StrEqual(cvarname, "lilac_enable", false)) {
		icvar[CVAR_ENABLE] = StringToInt(newValue, 10);
	} else if (StrEqual(cvarname, "lilac_sourcebans", false)) {
		icvar[CVAR_SB] = StringToInt(newValue, 10);

to:

	if ( convar == hCvar[CVAR_ENABLE] ) { // Store ConVar handles globally as Handle or ConVar (on new syntax) -typed
		icvar[CVAR_ENABLE] = StringToInt(newValue, 10);
	} else if ( convar == hCvar[CVAR_SB] ) {
		icvar[CVAR_SB] = StringToInt(newValue, 10);

	// etc...
	// The thing is that ConVar Handle is never changed after creating so you don't need to check for convar name
	// just directly check convar handle

Also, you should probably add translation support for hardcoded messages.
