This should make it easier to find the templates that are actually
part of the core webapp, instead of having them all mixed together
with the portico pages.
All links by default had an underline on hover, including when
<a> tags were wrapping <div> and <img> tags, which made for a small
underline near them on hover. This better focusses the underline
behavior to just paragraphs and lists.
This creates a dropdown in place of the normal register/login links
you get when logged out, with an option to go to the app or log out if
that appears you click on the avatar.
A bit more work is needed to make this look really good, but it's a
great start.
