Updated mediawiki/extensions Project: mediawiki/extensions/MobileFrontend e7c917cf6f9a30fd1c0e637b3d9cb3447af1b802

build: Remove unused packages 'jshint' and 'jscs'

Both the Makefile and Gruntfile use the grunt package which already depends on
jshint and jscs. A much newer version too, so npm is needlessly downloading
both and putting them in different (nested) node_modules directories.
