Add auto upgrader

[tadhgboyle]

• DB transactions don't seem to be working (ie: maintenance mode enabled, error happens, it's still enabled)
• Need a way to block multiple from running at once (locks on queue tasks?)
• Should we disable and then re-enable modules?
• Should we try to backup their DB first?
• Hide update banner if task is ongoing?
• Can we check ahead for any potential issues? (tmp not writable, ZipArchive doesn't exist)
• Utilize checksum to validate the zip before proceeding

Must check entire NamelessMC is writeable thought as ALOT of users dont have files writeable

Should also check disk usage

Currently a issue with disable/enable modules as i must load modules in a certain order
