an hour worth of work on this discord bot
to add a command for bot to use
.add "command name" "link to an image"
to replace the link for a given command
.add "command name" "link to a new image"
to display an image
."command name"
(no quote marks everywhere)
before launching the bot, make sure there's an empty file called commands.json in the directory, it'll store all the commands added via .add and in case of a shut down, all commands will be resored
