v3.7.0

• Full Raspberry Pi 5 functionality.
• Ability to launch in Firefox.
• Full-screen non-kiosk option for Chromium.
• Smarter auto-start procedure that waits for the clock server to be ready before opening a web browser, providing a message in the browser if the server fails to start in a timely manner.
• Improvements in monitoring GPS time performance.
• Other minor improvements, like a semi-successful work-around for a Chromium browser bug I had to report, one that will hopefully be fixed for real soon, now that my bug has been verified and assigned to a developer.
