Redo settings views to eliminate unnecessary borders
In the development branch, I've started working on the layout for the admin panel, and created a much nicer layout. I should apply it to the other settings views.
The biggest improvement is in the tabs. Rather than have the extra border and spacing like this:
border-top-0 eliminates the top border when the tabs are directly connected, and has a nice side effect where it adds the top border back when the current tab is not directly connected to the tab content.
