Add possibility to have host specific menu lines in tofi

For the Shift+SUPER custom menu I wanted to be able to add some
copy and paste things which I don't want to have everywhere
especially not uploaded and stored in git.

Now it's possible to have a aditional menu-{hostname}.list
where you can put extra things for this specific host. I added
there things like:

Phone=echo "012345678" | wl-copy

because I often need this specific phone number and don't want to need
to start the Contacts app and search for the number and copy it.

I'm planning to add more host specific things.
