Added feature to Mary-Bot that shows you a rendered preview of your article as soon as you post it. No need to wait for a full website regeneration. Also, the !regeneratewebsite is now faster because it doesn't recreate every single image thumbnail, only the text. There is a new command: !fullregeneratewebsite, which is basically the old !regeneratewebsite. I also added a slight amount of security to the !deletejournal command, to prevent slip-ups.
