Add volume for an item

Add the volume of an item.
For example:
<item slot="1" c="6" q="250" w="0.13" hp="447" dur="447" fob="165" e="e" v="2">icfja_3.sitem</item>

Don't know if you found a workaround for this one, but I'm interested too.

the alternative would be to put some ugly array in the code with the volume of typical items (armor pieces, jewels, forage material ..
etc.)

I don't understand why the Weight is given (which is almost useless except for weapons) and not the volume.
