Move game and fun commands to Fun folder, fix ddg

This moves all the fun commands and games into the fun folder.

This commit also makes changes to the duck_game.
It was setting a footer during an embed init, which is no longer
possible with the version of d.py we use. Additionally, an issue with
editing an embed that had a local image loaded.
The workaround for the time being is to update the message,
not the embed.
