玩家編輯（Player edit）視界

新增 ChangeLevel 訊息。從玩家編輯視界觸發這個訊息。

編輯 src/Players/Edit.elm 檔案，修改 btnLevelDecrease 及 btnLevelIncrease：

...
btnLevelDecrease : Player -> Html Msg
btnLevelDecrease player =
    a [ class "btn ml1 h1", onClick (ChangeLevel player.id -1) ]
        [ i [ class "fa fa-minus-circle" ] [] ]


btnLevelIncrease : Player -> Html Msg
btnLevelIncrease player =
    a [ class "btn ml1 h1", onClick (ChangeLevel player.id 1) ]
        [ i [ class "fa fa-plus-circle" ] [] ]

在這兩個按鈕新增 onClick (ChangeLevel player.id howMuch)。其中 howMuch 為 -1 來遞減等級，1 則是遞增。
