Little tweaks and corrections.

Clicking on image at Specifications page will now load the next image; link to the Ingenic CPU specification is added; Opera prefix for CSS transitions is added; FAQ answers unfold vertically and more fluently; press release date typo correction; text on About page is now justified; dir variable is deleted as it's not used in slideshow.js; '0px' is now just '0' in base.css; 'cursour: hand;' is removed from base.css because 'pointer' value is enough.
