Clean up filesystem

[spark-c]

Since the creation of this bot, a lot of new files and directories have been written; the filesystem ought to be cleaned up and organized better.

This will probably entail a few things, like:

• Creating a bot or src dir for code
• cogs/ will probably move there? Need to check other repos to see convention
• Moving baby-bot.py into that dir
• Might need to add a run.py in root dir?
• Will certainly need to update the Heroku PROCFILE to properly start the bot
• Perhaps adding a config/ dir

Of course, imports and the open()ing of files will need to be checked and updated.
