Change project structure

For the server and "client" to be able to communicate with eachother,
I'll be using DBus (https://www.freedesktop.org/wiki/Software/dbus/)
and the dbus-crate (https://crates.io/crates/dbus/).
Also, it will probably be better to split the server and client/daemon
and control utility in two separate projects (using Cargo's workspaces
(https://doc.rust-lang.org/cargo/reference/workspaces.html)).
