oga 1385b56548 - Remove the "all rights reserved" tag at the top of most of the source
files, and replace them with the actual ISC license.

- add license to the manpage (it was lacking before)

- correct license statement in the README

Permission given by Marius (copyright holder):
"1. please replace with the standard ISC license
2. you may add the ISC license to the man page
3. feel free to replace the information in the README as well"

and Dros (copyright holder for group.c):
"Please switch group.c to the ISC License."
