[2019] New crafting item tab

Thank you for the feedback.

We recently rewrote how items are stored. We wanted to include this work in Patch 0.7.5 due to it facilitating several improvements, and the tab in its current form was comparatively quick to implement. We do intend to replace it, though we aren’t yet ready to talk about future iterations of rune and glyph storage. Apologies for the worse quality of life in the meantime.
