After clicking "New Loadout" button, it creates new Tree, new Skill set and new Item set, which is horrible when you already have done these things.

Describe the solution you'd like

PoB should select the currently selected Passive Tree, currently selected Skill set and Currently selected Item set into the newly created Loadout, turning Loadouts into an easier to use feature, as with the current way you'd be locked to the newly created tree, skill set and item set, having to start from scratch in order to use the feature, as it ignores previously created pages.

首先定位 "New Loadout" 按钮的处理程序，以及选择当前 Passive Tree、Skill set 和 Item set 的代码。跟踪新的 Loadout 如何创建或选择这些页面。完成标准是：新的 Loadout 选择当前已选中的页面，而不是创建新的页面，同时保留现有的 Loadout 行为。
