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.

Added user*.less files to config

Fixed JavaScript compression. The compressor did not recognize a regular expression after a '&&' ot '||' operator. So it could happen that code had been cut off if the regular expression included '\//' (which was treated as a single line comment because of the regular expression not being recognized). Finally fixes #897.

Originally AUTH_USER_CHANGE handler could modify the user data, however,
auth plugin consequently worked with different copy of the array thus
effectively preventing any changes by the AUTH_USER_CHANGE implementer.

Otherwise comments are never visible in css.php
