Mbround18 #8 auto update

[mbround18]

Contributions:

• resolves Auto-Update #8 with two pieces
• Auto-Update #8 pt 1. Added auto update cron and env variable
• Auto-Update #8 pt 2. Removed if statement on odin install which will cause system to update the game each launch. It will not force re-download each time based on my local testing.
• Added file system responsibility aspect with the src/files module. Each file has a corresponding file that maps what available actions it has.
• Simplified logic in start and stop to provide a cleaner developing experience.

Note! With this change it changes how the odin start command operates! it now sends the output off to /dev/null but you can still view your servers command output by viewing output.log in the server directory

For those who are using this via docker, it should act the same by tailing the output.log
