[Plugin: Auto Thickbox] Notice Error while executing wp-con.php from crontab (patch included)

Hello,

One of my website has wp-cron.php setup as a crontab job. In that case, thickbox throws a notice error. Also the ?> at the end of PHP files is useless and may be a source of errors.

Here is the patch to solve that: https://gist.github.com/841744
