Update node.tpl.php

A number of changes were required to node.tpl.php:

* static has been renamed to sticky
* We should print the $submitted variable rather than the individual bits of information -- this allows admins to selectively disable/enable the information. (as the original submitter complained he/she could not)
* avatars have been renamed to user pictures (renamed the classes in style.css too)
* the print $picture outputs the appropriate div.picture, so it is no longer necessary to generate one separately

Patch attached.

Fixed.
