[IDB IGNORE] Music cassettes, walkmen, DJ station & (possible) play-internet-sound fix.

This is probably never going to be finished, but I like a space to organize things. Hashtag feel free to help. I'll add the rest of the PR body as development progresses.

About The Pull Request

This is a PR for the music system ported from MonkeStation, which adds music cassettes that can have tracks added to them, walkmen(mans?) and a DJ station that can be used by the curator to play server-wide internet sounds based on the tracks present in a cassette.

Cassettes

Players can take a blank cassette and use a cassette deck to add tracks to it using youtube links. Each cassette has two sides, each side fitting 7 tracks to it. Then, you can submit this cassette for admin review using a postbox - currently, it costs 5000 metacoins in order to submit a cassette. Since Doppler doesn't have use for metacoins, an alternative is needed. Maybe normal credits? Or for free?!

After submitting your cassette (and it gets approved), you can insert it into a walkman, where you can listen to music individually (it plays an internet sound only for you). Or you can play your cassette on a DJ station, which is (intended to be) located in the curator's study, granting the curator the attribution of a DJ. Through a DJ station, you can play the songs in a cassette to the whole server (there are some rules as to who can hear it - I /think/ it only plays to people who are in the station's Z-level, or the Z-level in which the DJ station is in).

Despite sounding simple, this system as a lot of codependencies, the biggest of which being Floxy. Floxy is MonkeStation's workaround for Youtube-dl - it's a proxy service that can be used to relay youtube sounds to the server, since YT-dl is super hyper illegal now </3. The media co-dependencies are also quite complex to get around.

• Fix basic systems;
• Solve compatibility issues;
• Fix tgui (MS uses React UI);
• Sort Floxy out (or another proxy that serves as a yt-dl workaround) - needs operator help;
• Add the cassette library;
• Organize modular files (pretty messy right now);
• Adapt to be Doppler-compliant (you need metacoins to submit a cassette - Doppler doesn't use those);
• Get rid of MS dependencies/code;
• Add assets to maps.

Fix tgui (MS uses React UI);

modern tg and its forks, including doppler, also use react ui, lol

also, may be worth looking at Monkestation/OculisStation#116 - it has a modular implementation of the Floxy subsystem.
