Copyright notices

[Steve_B]

I have been updating some of the copyright notices so that they reflect the current pfSense copyright status. It has been pointed out that in doing that I incorrectly dropped some copyright holders.

Wherever individual copyright exists I now take every care to preserve it in the file headers. It is always possible that mistakes were made, however. I have made many thousands of edits to this project in the last few months, and I make as many typos and ^C/^V errors as anyone. (Probably more :)) If you notice a copyright error or omission, please report it here so that I can correct it without delay.

Conspiracy theorists, tick-tocks, and others not withstanding, I am working to correct any such errors as quickly as possible.

Please remember this is Alpha software. We will make sure everything is correct before general release.
