i made printing less complicated by making printing both the name and
the url with the seperator the default option and using both those flags
at the same time should do the same thing as just printing without any
flags.
i also refactored commands into their own module folder with each
command getting their own file module.
the cli now uses a new module in the shared crate, called directories
which is a module that has functions for directory stuff, mainly, it
uses the directories crate to have a portable way to have directories
for the application like data directories and config directories.
i also added logging to the shared and cli crates, so you can see debug
stuff with the RUST_LOG environment variable.
