Missing Escaping

[tomjn]

These locations are missing escaping:

• https://github.com/stuttter/wp-spider-cache/blob/master/wp-spider-cache.php#L735
• https://github.com/stuttter/wp-spider-cache/blob/master/wp-spider-cache.php#L970

Some places with questionable security:

• https://github.com/stuttter/wp-spider-cache/blob/master/wp-spider-cache.php#L703
• https://github.com/stuttter/wp-spider-cache/blob/master/wp-spider-cache.php#L526

Some places could do with outputting rather than returning markup so that they can be escaped at output rather than early escaped, do_row is a prime offender:

https://github.com/stuttter/wp-spider-cache/blob/master/wp-spider-cache.php#L863

Otherwise the code looks good, sprintf used correctly for translations, and translations escaped effectively, very nice
