Changed the documentation URL to match Karma version 0.12

Actual: "Karma's docs http://karma-runner.github.io/0.8/plus/RequireJS.html"
Expected: "Karma's docs http://karma-runner.github.io/0.12/plus/requirejs.html" *OR*
"Karma's docs http://karma-runner.github.io/0.12/plus/RequireJS.html"

Also links from the 0.8/plus/RequireJS.html to the 0.12 version are broken due to differences in letter captitalization. Signed-off-by: Bogdan Bivolaru <osbiv@yahoo.com>
