settings: Make settings overlay more responsive.

This doesn't completely fix settings responsiveness, but it's a big
step along the way.  Outstanding issues include:

1. When switching tabs from settings to organization, it will launch
the first item which is more annoying in this view since it brings you
into that tab. Haven’t decided on an elegant solution to this yet.

2. Sidebar scrolling doesn’t work. I have to restructure how the top
section and bottom sections of content are displayed to fix this.
Likely by enforcing min-height of 100% - bottom height on the top piece.

3. Most of it is actually reasonably responsive but some isn’t, and
should be fixed on a case-by-case.
