A calmer launcher, and Modrinth mods

Fewer boxes everywhere, a Mods page that browses and installs mods from Modrinth, and redeem codes that work the moment they are made.

• Settings, Play, Controls and News rebuilt without a box round every row - plain rows parted by thin lines.
• Mods now browses Modrinth: search, sort and filter Fabric mods for 1.21.4, and install them with one click.
• Redeem codes are checked online, so a new code works straight away and can only be used once.
• Memory shows what your computer has and what the running game really got.
• A new battle pass icon, a brighter Shop and Coins tab, and real updates on this page.
