- Modified item buying logic: selected items are purchased immediately without having to click the "buy" button, and they stay in the list of purchased items until the round is started. (-> It's possible to see which items have been purchased and cancel purchases).

- Clients can be given a permission to manage the campaign (atm selecting which location to head towards and buying items).
- Syncing cargomanager state with clients.
- Misc fixes.
