 (#49)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- Make button "Delete all" remove only orders from current selected power.
- Reorganize code
- [web] Remove bugged and useless function gameReloaded() from game page.
- This function caused error `engine.getPhaseType is not a function` for
  games with deadlines.
- Move function saveGameToDisk into its own file.
- [web] Add documentation to methods involved in orders management to help understand what happens.
- Move methods getServerOrders() from game GUI component to game engine object.
- Rename method onSetNoOrders to onSetEmptyOrdersSet.
- Rename property in PowerActionsForm: onNoOrders => onPass.
- [web] Update sending orders to send request clearOrders when local orders list is null.

- Renamed local file:
  - components/power_order => power_orders
  - forms/power_actions_form => power_order_creation_form

- Move power orders buttons bar to a separate file:
  - components/power_orders_actions_bar

- [web] Improve messages about local/server defined orders.
