Support !important in nested mixins #314

	# While the GitHub mirror is read-only, we keep this CI config
	# for convenience to forks and pull requests.
	#
	# To submit a patch you can:
	#
	# * Create a Wikimedia Developer account and submit it to Wikimedia Gerrit
	# <https://www.mediawiki.org/wiki/Developer_account>,
	#
	# * Or, submit the output of `git diff origin/HEAD`
	# via <https://gerrit-patch-uploader.toolforge.org/>.
	#
	# * Or, create a pull request via GitHub and wait for someone
	# else to do one of the above.
