Tinyauth v4.0.1

Hey everyone, this is a simple patch release to fix some issues that occurred with v4.

Improvements

• Move docker connection check to start-up so as label discovery can fail in case of a socket proxy crash
• Use GIN recovery module to translate panics to 500 errors
• Sort OAuth providers based on name length
• Allow root cookie domain redirects
• Use more verbose logging for the trace log level

Fixes

• Ensure data directory exists on docker images
• Remove trailing spaces before checking OAuth username and name
• Do not use container name for label discovery

Technical

• Use docker meta flavors for images
• Bump dependencies

Please let me know of any issues so as I can fix them as soon as possible.
