Wildcard support for IP-banlist

Today I added wildcard support for the IP-banning feature, 185.32.43.* will ban all IP-adresses that start with 185.32.43. But, for the new ban-system to work you HAVE to add every new IP/IP-group(using wildcards) at a new line. Remember that you can add comments in each line after //

Here's an properly formatted banlist as an example:

167.34.25.64 //Spammer
//53.43.65.23 This one will not be banned because the ip is commented out with "//"
45.64.23.* //All IPs that begin with 45.64.23. will be banned (use with caution)
*.*.34.* //All IPs where the third number is 34 will be banned (use with caution)
