cleanup before exit
This was previously done by the systemd service. But since we allowed
changing the name of bat0 and bridge0, we can't expect systemd to still
do that job. Commented out some lines in the systemd service and made it
send SIGINT instead of the default SIGTERM to kill naxalnet. I
accidentally used to increment a2, a3, a4, ... in the __version__
instead of dev1, dev2, &c. a few commits back. Removed some print()
lines lurking somewhere in the code. The cleanup is still not completed.
We still have to delete the interfaces bridge0 and bat0, or whatever
name the user gives it. Just out of boredom, I added some description to
some network configuration, though so I doubt if anyone will understand
it more because of that.
