the 's' flag tells preg_match to operate in multi-line mode. the 'm' flag does the same, but allows line begin and ends to still be matched which is useful in some cases.
Added a single short flag for every long flag and a single long flag for every short flag.
This now gives us 2 ways to set each flag.
Also updated the showhelp.
Dropped an unnecessary 'else' statement.
The pattern files are large and complex enough to justify some whitespace and comments to explain what each entry is.
Added logic to check if the line is empty or if the first character is equal to '#' before using it as a pattern. Simply skips over empty and commented lines.
Added Extra Patterns for scanning from samples i found on my server.
Added extra-check it checks for googlebot and htaccess useful for cleaning up left over files.
