source: remove names from source comments

Several reasons:

- we can't add everyone who's helping out so its unfair to just a few
selected ones.
- we already list all helpers in THANKS and in RELEASE-NOTES for each
release
- we don't want to give the impression that some parts of the code is
"owned" or "controlled" by specific persons
