This changes the layout of administration for non-administrators such
that they can view organization settings and emoji settings and
displays everything as readonly unless they have the capability to edit.
For now, we just enabled this for the emoji settings and organization
settings features.
This restructures the styling for the Zulip settings and
administration pages to minimize use of Bootstrap and use a consistent
styling library for similar elements.
While it is basically a wash in terms of the page's visuals, it will
make our life a lot easier for future work on improving the settings
pages section of the site.
