#124 Support for item (object) placement in homes

Ability to place items in homes, save into the database, move around the house and pickup needs to be made available.

Secondly basic access restrictions so that only owner can edit the house objects.

Outstanding items:

• Outside door widget needs house windows working correctly, first panel my houses not listed. Payment due not obvious. Visit tab not useable when opening access/your house.
• Accessing the house via the 'visit panel' when you are owner and also using /house command inside a house (equivalent to 'access' on the door widget inside).
• need to add an additional column to spawn_instance_data for unique_item_id
• Inside door widget needs listing of all items in the house (Depends on 2nd item)
• Initial buying of house needs to remove coin like upkeep payments do
• Access needs to be restricted to city zones (you can access the house anywhere right now)

collection of sql updates for notes

  update commands set handler=514 where command='house_ui';
  update commands set handler=515 where command='house';
  update commands set handler=516 where command='move_item';
  update commands set handler=517 where command='pickup';
  alter table spawn_instance_data add column pickup_unique_item_id int(10) unsigned not null default 0;

There is no DB setup for city zones right now so I am not going to program in something that needs additional DB work, will open a separate item for now.
