Script command: itemlink to generate <ITEML> 1.0.1

To simple generate <ITEML> string by using itemlink. <ITEML> is string that auto-parsed by client that support item link feature, when user SHIFT+Click the item or equipment.

Quote

*itemlink(<item_id>{,<refine>,<card0>,<card1>,<card2>,<card3>});
*itemlink2(<item_id>,<refine>,<card0>,<card1>,<card2>,<card3>,<RandomIDArray>,<RandomValueArray>,<RandomParamArray>);

Generate <ITEML> string for an item and can be used for npctalk, message,
dispbottom, and broadcast commands. The result is clickable-item name just
like from SHIFT+Click from player's inventory/cart/equipment window. In mes
command is still usable but the item name is not clickable.

Examples:

    npctalk "Knife [3] : "+itemlink(1202)+"";
    npctalk "+16 Knife [3] : "+itemlink(1202,16)+"";
    npctalk "+13 BXB Bapho+VR+EA2+EA1 : "+itemlink(18110,13,4147,4407,4833,4832)+"";
    setarray .@opt_ids[0],RDMOPT_VAR_ATKPERCENT,RDMOPT_VAR_ATKPERCENT,RDMOPT_VAR_ATTMPOWER,0,0;
    setarray .@opt_values[0],3,5,20,0,0;
    setarray .@opt_params[0],0,0,0,0,0;
    npctalk "+13 BXB Bapho+VR+EA2+EA1 + 3 Options : "+itemlink2(18110,13,4147,4407,4833,4832,.@opt_ids,.@opt_values,.@opt_params)+"";

For RandomIDArray, RandomValueArray, and RandomParamArray only works if
client (& server is complied) with supporter Item Random Options feature is
PACKETVER >= 20150225. But using itemlink2, all command parameters must be
specified if PACKETVER is not supported, use dummy arrays to avoid errors!
