Changed matching algorithm to string

Example for a dangerous entry: dropbox.com with the hostname algorithm and url as a valid attribute type means that https://dropbox.com/malicious/files.exe would get excluded from the automation systems when using the warninglist.

I've changed the algorithm to full string matches.
