Replace small-menu.js with navigation.js inspired by Twenty Twelve.

Doesn't use jQuery, slightly easier to understand, uses a media query for max-width, rather than JS events making it faster to respond.
Corrected two typos

"don't" with &apos; should be more correct than &rsquot; (or is it better to escape it \' ?)
I personally find the line * translators: %1$s: smiley */ pretty confusing, but at least it should be singular (not smilies)
Password Inputs

Adds password input types to styles for text and email inputs.
Load comments template only when comments are open or there's at least one comment

To be consistent with single.php and to ensure that an empty div (<div
id="comments" class="comments-area">) isn't outputted when both
comments are closed and there aren't any comments.
_s: Make sure images with height attributes in comments are scaled
correctly.
On hashchange, make sure we set focus for elements that need it. Essentially the same as 136, but without jquery
