Register the `OnWindowResize` listener in the engine client instead of the game client and properly dispatch the event also to the editor, so text containers in the editor are cleared when the window is resized.
Closes#7018.
Show a short message below the existing chat mentions message that is shown in the top left area of the editor above the layers/images/sounds button when the player character is moved ingame while the editor is open. The messages are cleared when the editor is activated and when the client is disconnected.
Closes#1993.
The `Append` method was returning `0` on success while `Load` and `Save` were returning `1`.
Now all three methods use a `bool` as return value and return `true` on success.
The call `SortImages()` is moved inside the `Append` method, as it should always be called when appending succeeded.
Purely automatic change. In case of conflict with this change, apply the
