Remove TUI (search) & rework play

[Ratakor]

Remove the TUI and search command because:

• I don't use it.
• It depends on libc, multiple library written in C, longjmp.
• It depends on the unmaintained zig-spoon that I cba maintaining.

Rework play command:

Why:

• Because it forces the user to use a dmenu-like program.
• It's not extensible.

How:

• A new list command, see TODO in README.md.
• Also this feature should probably be done in another PR.
