Make sure we always checks for failed validation, before redirecting.
A positive return value does not signal that all settings were able
to be written, only that at least one was - errors still need to be
checked!
The page admin/search.php is the default administration page in Boost
based themes. It should behave the same as admin/index.php or
my/index.php and check if the site needs upgrade.
Admin search page was processing the blocks delete request before the blocks
could process it.
Added a hidden field to the search results form so it can be sure the form submission
was for saving admin settings.
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!).
