Upgraded grunt-jscs to version 0.8.

Implemented new JSCS rules.
Tweaked tooltip section CSS to avoid wrapping.

It seems that the inline-block without width and bottom margin were
confusing Chrome and IE a bit when combined with the avoid break column
rules. This change keeps the tooltips properly structured.
Updated the Sunderer AMS skill definition.
