Code improvement for uksmctl and uksmstat

Hi Oleksandr.

I thought I share some changes I made on your code:

...

In detail:

- removed the copyright notice from the output --> belongs to the
LICENCE
file
- removed the short description from the output --> belongs to the
README
file
- added the examples from your github page to the output
- added long parameters
- uksmctl: renamed --state to --toggle
- uksmstat: renamed --saved to --shared

Greetings

Ikem
