Adapted the client to the latest server changes.

There are two bugs left I'll take care about in the near future:

- Items dealing with more than one slot capacity
are only showing on the first equip slot.
- The unequip button doesn't get updated when clicking
on the equipped item.

A client design limitation known:
- The client still don't handle correctly items applied on more
than one item type at equip time.
