label and update list rework (#229)

* Reformatting the updates available list

* rewritten list padding to be dynamic

* Label rework + clearer messages (#228)

- Moved up label check and logic to earlier in the process, to iterate the whole run the same way if `-l` option is passed.
- Added messaging to make it clearer.
- Clarified Readme and --help message.
- Clarified prune message (to mean ALL dangling, not just currently updated).
