Added phishing protection
I've added phishing protection to the Discord bot used on Nexe's Discord server. The bot uses the CERT Poland's database of phishing domains. When the bot detects a message with a phishing domain in it, it immediately deletes it, mutes the user and notifies the moderation team, which can make a decision whether the mute was justified by pressing one button.

This is pretty important right now, as Discord has recently been flooded with loads of fake steamcommunity links which steal your Discord account and spread to more users using your account. This solution is much better than the old one, where we had a manually updated list of every word that was blocked in a message.
