Update AngularJS modules to 1.1.1 too.

AngularJS was being included from 1.1.1 but the resource and cookies
module was being included from 1.0.7, made them match.
CSS overhaul of judge page.

Centered the voting area.

Also got rid of the borders and use very light background color instead.

Removed the fixed width height for the answers but not sure if that's a
good move.

Note, need to add question title to the judge page.
