Statistics CSS changes and Survey Page

Statistics got some basic CSS changes that stopped weird behavior with the graphs within the wells.
Survey page has now been formally added. Survey.php is the front end, surback.php is the backend. Survey.php will show the available surveys (possible ones: registration and gold badge). Surback.php can be used to embed a survey anywhere within the site as long as it's included or required in PHP (see readme at the beginning of surback.php for details).
