Can draw bernie_active on minisign, but no icon

When Bernie comes alive but doesn't turn into BERNIE!, he can be picked up directly; this is achieved by giving him an inventoryitem. As such, and since he can exist out in the world, he can be drawn on a Mini Sign. However, he doesn't seem to have an inventory have an associated inventory image (or whatever gets used by drawable exactly), so you can end up with a drawn Mini Sign that looks blank.
