In an older version of PHP a file_exists() call would issue a warning
when the file did not exist. This was fixed in later PHP releases. Since
we require PHP 5.3 now, there's no need to supress any error here
anymore. This might even give a minor performance boost.

As described in the common idioms of the HTML5 spec, mark up navigation as a list inside a `nav` element for better semantics and accessibility.

for discussion and background.

Add the class .bounce to any element to let it bounce slightly for 2
seconds. This is useful to make the user aware of some element. Can be
combined with #scroll__here when a long list auto scrolls to a certain
item.

This adds a subtle animation effect when scrolling to the #scroll__here
behaviour ID. It also adds a 100px offset to make the object not stick
to the browser border.
