Moved <style> section

The style tags placed between 

``` php
<?php echo $header; ?><?php echo $column_left; ?><?php echo $column_right; ?>
```

and

```
<div id="content"><?php echo $content_top; ?>
```

cause the default CSS properties of 

```
#column-left + #column-right + #content, #column-left + #content{
```

to be ignored.  Page layout is displayed incorrectly as a result.

Moving the style tags below the content div seems to fix the problem.
