Subject: redesign cli

This is a major rebuilding of the CLI. The library part is split out
into pkilib and the cli handles only the communication with the user,
I/O and the library.
The API will still look the same, but the code should be much better to
grasp. Instead of repeating everything, more will be grouped together
and reused.
