We add a new theme config so the theme can say it supports font-awesome.
If this is true, the pix_icon renderer will call a mapping function to map
from the moodle style t/edit to a font-awesome style fa-cog icon name. Then the renderer
will either render an image tag for old icons - or an accessible font-awesome <i> tag.
This mostly works - but there are some places where we don't use the pix icon renderer, and
we directly create image tags with pix_url image sources. These will need updating (Atto icons,
drag and drop move icons, editpdf icons).
There are 2 kinds of blocks that are undeletable. Those required by the
theme and those protected via the admin page ui. We only want the theme
ones to be auto created site wide if they don't exist - so we need to
rename the theme ones and split the logic.
Center logo / site name.
Add padding to logo / site name.
Serve retina images and resize with css.
Add a line under the logo / site name.
Don't show site name if there is a logo.
Obey nonavbar option in core_renderer.
This patch includes a big set of changes that are all designed to work together to provide
a better way to navigate in the new theme, and a different way of working with blocks.
Blocks have been moved to a "drawer" that can be opened and closed (this is remembered in a user pref).
A new "flat navigation" element is also available in a drawer - which should let you do 90% of things
without needing to open the "blocks" drawer.
The flat navigation is build from specific parts of the nav tree - the top nodes like "calendar, dashboard" are
hand picked. There is a mycourses node listing your enrolled courses.
There is a node for the current course, built from the top nodes in the current course node in the nav tree.
Administrators have a link to the Site admin settings here too.
These nav elements are used by the templates for the new theme, which also has a resigned layout for login and signup.
There have also been some additional fixes / improvements to the scss for the new theme which goes along with these
layout changes.
This set of changes is a collaboration between Martin, Damyon and Alberto (thanks!).
