[crossfire] Ground and container view

[James Lopeman]

The container change works out fairly well on the GTK2 client. It also 
prevents disconnects when you have a bag full of rings and such.

Unlimited ground view and container view have a large number of issues. 
Even inventory view CAN ( and has ) caused client disconects. 

Containers like ground can hold huge lists and its safter and more consistent 
for them to be .. consistent.
