Add bank tag builder

[Pheubel]

Creating bank tags inside of Runelite itself can be quite clunky and time consuming and when you don't own an item, it becomes a lot more annoying to add a tag to it. It would be nice if you could create a tag on the website where you can search for items to add to the list. It would be a nice compliment to the visualizer of exported tags to give it more functionality.
