The Requirements class currently treats only absolute URLs as URLs, and
tries to interpret anything else as a filesystem path. This prevents
using scheme-relative URLs for requirements.
Example:
<% require javascript(//ajax.googleapis.com/ajax/libs/jquery/1.7.2/jquery.min.js) %>
This forces the unfortunate choice of not using a CDN for common
scripts, always using an https absolute URL, or accepting that some
browsers will throw a security warning when viewing the site in https.
This change allows scheme-relative URLs & updates RequirementsTest.
2.4 used to use a manifest to find css. One side-effect of that is that even without explicit support,
css files in module-specific themes (/themes/{theme}_{module}/) would get picked up. This broke in 3.
This fix does still require the module name to be explicitly passed as a parameter to themedCSS, but if
you do, and a css file of that name exists in the module-specific themes css directory, that will
be included in preference to the theme or module provided css
