v0.1.0-beta.2

Added

• License Tellyard under Apache 2.0, with a NOTICE for the name and the software in the image.
• Add a Legal section to the README.
• Add documentation pages for channels, Plex, how it works, troubleshooting and maintenance.
• Add a security policy, contributing guide and issue templates.
• Publish the image for 64-bit ARM as well as Intel and AMD.
• Add the Tellyard logo and a landing page at tellyard.sandobserver.com.

Changed

• Point the install steps at the beta image tag until the first stable release.

Removed

• Remove the start-up cleanup of artwork files left by early test builds.

Fixed

• End a show when the next one starts, so overlapping listings from a guide source no longer collide.
