Fix PHP Product Class and Stats PHP errors
Errors were result of instantiating a product using a product id corresponding to a product that was deleted.  As this is a normal occurrence as products come and go from a store the instantiation isn't the problem, but doing some operations on it is a problem.

Before doing these operations a check is made to see if they are permitted.
Product category image should only be displayed in the image column in the admin, rather than all custom columns.
Streamline wpsc_custom_category_column_data() and adhere to coding standards.
Cleanup formatting and add documentation for wpsc_custom_category_column_data().
Remove unused global $wpdb in wpsc_custom_category_column_data().

Remove esc_html() call from around an array
Remove a hidden pass by reference

I've been getting a lot of "PHP Strict standards:  Only variables should be passed by reference in /Users/John/Sites/wpec-dev/wp-content/plugins/wp-e-commerce/wpsc-components/theme-engine-v1/helpers/template-tags.php on line 647" in my debug.log, and discovered that the pass-by-reference is happening because array_shift() is being passed the result of an explode(). This removes that, and yoda-izes a the if condition.
Remove forgotten debug code.
