This commit updates ephemetoot for version 3.0.0-alpha.0
Version 3 is designed to be installed from PyPi rather than GitHub. This means the default plist and config files will not be available.
- updates to directory structure
- add --init flag for initiating a config file
- change --schedule so that it saves the plist file directly to ~/Library/LaunchAgents
- update documentation
- new README just for PyPi
