preg_match warning when

@kenrbnsn can you isolate this to only one of the additional patterns you're introducing?
Also, have you changed the default patterns below at all?

/.*\.aspx/
/.*\.asp/
/.*\.jsp/
/\/blog_edit\.php/
/\/blogs\.php/
/\/wp-admin.*/
/\/wp-login.*/
/\/my_blogs/
/\/system\/.*\.php/
/.*systopice.*/
/.*login.json/
/\/episerver.*/

Hello @kenrbnsn, please review and merge the PR: !28

I installed the patch on my site and the PHP warnings went away.
