Fix to API navigation in Safari

[remy@…]

The navigation for the API is broken in Safari, currently showing a list of random letters (mostly Js and Ss).

The bug is being caused by difference between the DOM in Safari.

The following line in 'js/doc.js:29':

return $.fn.text.apply( [a.childNodes[1]] ).replace(/^$./,"").substr(0,1).toUpperCase();

Should be changed to:

return $.fn.text.apply( [a.getElementsByTagName('SPAN')[2]] ).replace(/^$./,"").substr(0,1).toUpperCase();

The current API docs will be replaced with a new version soon that doesn't have that bug anymore.
