build: Bump most devDependencies to latest

 grunt-stylelint         0.10.0  →  0.10.1
 karma                    2.0.2  →   3.0.0
 karma-firefox-launcher   1.0.1  →   1.1.0
 karma-qunit              2.0.1  →   2.1.0
 postcss-less             1.1.5  →   2.0.0

This reduces our `npm audit` alerts down to just those from grunt-karma.
