Minor Improvements to the settings navigation

[GamerFlix]

Currently if one navigates into one of the main sub menus, from there navigates into one of the sub menus of that tab and then clicks the back button they are thrown back into the system helpers tab instead of the previous tab they were in. Example Navigate into the npc feature helpers of the 5e-helpers settings. Then navigate into the Undead Fortitude helpers If you now click the "back"-button you end up in the system helpers tab opposed to the npc feature helpers tab like one would expect.

Suggestion: Revert to the last visited subtab on clicking back instead. As the subtabs are directly mapped to the primary tabs there should be no caching needed.
