Add batch pickup on the pickup key for the server mt_pickup command

Embedded module mt_pickup wraps GameWindow.PickUpItem (Z / `): with batch
pickup on it sends /mt_pickup 1 MASK (0.5 s gap, one in flight, presses
swallowed while waiting); after 3 s without a reply it notes once in chat
and falls back to the original single pickup. Settings window (on/off and
8 categories, persisted in mt_pickup.cfg) behind a "拾取" button under the
switchbot entry by the minimap.

Live tested against 203 (channel-5 test core, port 13040) with the macOS
native client.
