trim() expects parameter 1 to be string

Some users report seeing the following warning in the WordPress Dashboard:

Warning: trim() expects parameter 1 to be string, array given in /home/..../wp-content/plugins/zencache-pro/zencache-pro.inc.php on line 967

Line 967 in zencache-pro.inc.php: https://github.com/websharks/zencache-pro/blob/000000-dev/zencache-pro/zencache-pro.inc.php#L967

That is a bug. The call to array_map('trim', assumes that $_REQUEST will contain all scalar values. A new method should be added (it may already exist), called trim_deep().
