5.6: tiny quality of life improvements

- remember celebratory emoji changes? they've been fixed, and are now dynamically loaded!
- changelog history now lets you try to load it again if first attempt failed for whatever reason.
- added glow to the donation button to make it more visible.
- cleaned up frontend js a little bit.
- updated some links in tests.
