Syntax: container <name> size <amount to increase>
container <name> weight <amount to increase>
container <name> restrict <item type>
The container command is used to increase the max item or weight capacity
of a bag. The cost to increase item capacity is amount*100 in questpoints.
The cost to increase weight capacity is amount*100 in gold.
The syntax 'container <name> restrict <item type>' will allow only the
specified item types to be placed inside the bag. The container can have up
to 5 item type restrictions, but only if the container itself does not
already have restrictions by default (the scrabble bag, for example). To
remove a restriction, use the same syntax. The cost to add one is 5000 gold
and 1000 questpoints. Removal is free.
