Consider adding csdb.dk browser

[vonmillhausen]

Vice3DS already has an excellent browser built in for Gamebase64, which gives in-app access to the vast majority of commercially released C64 software. It would be cool to also add a browser for https://csdb.dk, which would provide access to the largest collection of community generated C64 software as well - things like scene demos, music releases, graphics, etc..

If it helps with getting a head-start on the data side of things, VirtualC64 Web has a csdb.dk browser built into it: https://github.com/vc64web/virtualc64web
