 Expect to see more dependencies in Cargo.toml eliminated soon.

+1. `rodio` is unlikely to ever be eliminated (simply because audio is *complex*), and it's optional (if the audio player is not wanted). The dependency which provides hashing will also not be removed as I am not a cryptographer and not (quite) stupid enough to pretend being one
+2. `bmp-rust` is written by me and so isn't technically an external dependency
+
+> ### Update
+> Ignoring the audio player dependencies and `bmp-rust`, the only dependencies not written by me are now `libc` for libc Rust bindings and `bitcoin-hashes` for SHA-512 password hashing (yes, I know SHA-512 is not the greatest password hash function, but it is lightweight, relatively).
+>
+> Prior dependencies like `termion`, `linux_framebuffer`, `pty-process`, have been removed and replaced by a me-written version in the `linux` crate. As of v1.1, the dependency removing goal has been achieved. Huzzah!
